8 Overview of Energy bsorption Theory s companies strive to increase productivity by operating machinery at higher speeds, often the results are increased noise, damage to machinery/products, and excessive vibration. t the same time, safety and machine reliability is decreased. variety of products are commonly used to solve these problems. However, they vary greatly in effectiveness and operation. Typical products used include rubber bumpers, springs, cylinder cushions and shock absorbers. The following illustrations compare how the most common products perform: ll moving objects possess kinetic energy. The amount of energy is dependent upon weight and velocity. mechanical device that produces forces diametrically opposed to the direction of motion must be used to bring a moving object to rest. Rubber bumpers and springs, although very inexpensive, have an undesirable recoil effect. Most of the energy absorbed by these at impact is actually stored. This stored energy is returned to the load, producing rebound and the potential for damage to the load or machinery. Rubber bumpers and springs initially provide low resisting force which increases with the stroke. Cylinder cushions are limited in their range of operation. Most often they are not capable of absorbing energy generated by the system. By design, cushions have a relatively short stroke and operate at low pressures resulting in very low energy absorption. The remaining energy is transferred to the system, causing shock loading and vibration. Shock absorbers provide controlled, predictable deceleration. These products work by converting kinetic energy to thermal energy. More specifically, motion applied to the piston of a hydraulic shock absorber pressurizes the fluid and forces it to flow through restricting orifices, causing the fluid to heat rapidly. The thermal energy is then transferred to the cylinder body and harmlessly dissipated to the atmosphere. The advantages of using shock absorbers include: 1. Longer Machine Life The use of shock absorbers significantly reduces shock and vibration to machinery. This eliminates machinery damage, reduces downtime and maintenance costs, while increasing machine life.. Higher Operating Speeds Machines can be operated at higher speeds because shock absorbers control or gently stop moving objects. Therefore, production rates can be increased. 3. Improved Production Quality Harmful side effects of motion, such as noise, vibration and damaging impacts, are moderated or eliminated so the quality of production is improved. Therefore, tolerances and fits are easier to maintain. 4. Safer Machinery Operation Shock absorbers protect machinery and equipment operators by offering predictable, reliable and controlled deceleration. They can also be designed to meet specified safety standards, when required. 5. Competitive dvantage Machines become more valuable because of increased productivity, longer life, lower maintenance costs and safer operation. utomotive vs. Industrial Shock bsorbers It is important to understand the differences that exist between the standard automotive-style shock absorber and the industrial shock absorber. The automotive style employs the deflective beam and washer method of orificing. Industrial shock absorbers utilize single orifice, multi-orifice and metering pin configurations. The automotive type maintains a damping force which varies in direct proportion to the velocity of the piston, while the damping force in the industrial type varies in proportion to the square of the piston velocity. In addition, the damping force of the automotive type is independent of the stroke position while the damping force associated with the industrial type can be designed either dependent or independent of stroke position. 3

9 Overview of Energy bsorption Theory Equally as important, automotive-style shock absorbers are designed to absorb only a specific amount of input energy. This means that, for any given geometric size of automotive shock absorber, it will have a limited amount of absorption capability compared to the industrial type. This is explained by observing the structural design of the automotive type and the lower strength of materials commonly used. These materials can withstand the lower pressures commonly found in this type. The industrial counterpart of shock absorber uses higher strength materials, enabling it to function at higher damping forces. djustment Techniques properly adjusted shock absorber safely dissipates energy, reducing damaging shock loads and noise levels. For optimum adjustment setting see useable adjustment setting graphs. Watching and listening to a shock absorber as it functions aids in proper adjustment. Damping Force Min. Max. To correctly adjust a shock absorber, set the adjustment knob at zero () prior to system engagement. Cycle the mechanism and observe deceleration of the system. If damping appears too soft (unit strokes with no visual deceleration and bangs at end of stroke), move indicator to next largest number. djustments must be made in gradual increments to avoid internal damage to the unit (e.g., adjust from to 1, not to 4). Increase adjustment setting until smooth deceleration or control is achieved and negligible noise is heard when the system starts either to decelerate or comes to rest. When abrupt deceleration occurs at the beginning of the stroke (banging at impact), the adjustment setting must be moved to a lower number to allow smooth deceleration. If the shock absorber adjustment knob is set at the high end of the adjustment scale and abrupt deceleration occurs at the end of the stroke, a larger unit may be required. Shock bsorber Performance When Weight or Impact Velocity Vary When conditions change from the original calculated data or actual input, a shock absorber s performance can be greatly affected, causing failure or degradation of performance. Variations in input conditions after a shock absorber has been installed can cause internal damage, or at the very least, can result in unwanted damping performance. Variations in weight or impact velocity can be seen by examining the following energy curves: Varying Impact Weight: Increasing the impact weight (impact velocity remains unchanged), without reorificing or readjustment will result in increased damping force at the end of the stroke. Figure 1 depicts this undesirable bottoming peak force. This force is then transferred to the mounting structure and impacting load. Figure 1 Varying Impact Velocity: Increasing impact velocity (weight remains the same) results in a radical change in the resultant shock force. Shock absorbers are velocity conscious products; therefore, the critical relationship to impact velocity must be carefully monitored. Figure depicts the substantial change in shock force that occurs when the velocity is increased. Variations from original design data or errors in original data may cause damage to mounting structures and systems, or result in shock absorber failure if the shock force limits are exceeded.

10 ShockCover5-B-4-English /6/4 1:5 M Page 5 Sizing Examples SHOCK BSORBER SIZING RTE CONTROL SIZING Follow the next six steps to manually size Enidine shock absorbers. Follow the next five steps to manually size Enidine rate controls: STEP 1: Identify the following parameters. These must be known for all energy absorption calculations. Variations or additional information may be required in some cases. ) The weight of the load to be stopped (kg). B) The velocity of the load upon impact with the shock absorber (m/sec). C) External (propelling) forces acting on the load in (N), if any. D) The cyclic frequency at which the shock absorber will operate. E) Orientation of the application s motion (i.e. horizontal, vertical up, vertical down, inclined, rotary horizontal, rotary vertical up, rotary vertical down). NOTE: For rotary applications, it is necessary to determine the radius of gyration (K) and the mass moment of inertia (I). Both of these terms locate the mass of a rotating object with respect to the pivot point. It is also necessary to determine the angular velocity (ω) and the torque (T). STEP : Calculate the kinetic energy of the moving object. W x V I ω EK = (linear) or EK = (rotary) Utilizing the Product Locator for Shock bsorbers located at the beginning of each product family section, select a model, either adjustable or non-adjustable, with a greater energy per cycle capacity than the value just calculated. STEP 3: Calculate the work energy input from any external (propelling) forces acting on the load, using the stroke of the model selected in Step. T EW = FD x S (linear) or EW = R x S (rotary) S Caution: The propelling force must not exceed the maximum propelling force listed for the model chosen. If the propelling force is too high, select a larger model and recalculate the work energy. STEP 4: Calculate the total energy per cycle. ET = EK + EW The model selected must have at least this much energy capacity. If not, select a model with greater energy capacity and return to Step 3. STEP 5: Calculate the energy that must be absorbed per hour. Even though the shock absorber can absorb the energy in a single impact, it may not be able to dissipate the heat generated if the cycle rate is too high. E TC = E T x C The model selected must have an energy per hour capacity greater than this. If it is not greater, there are two options: 1. Choose another model that has more energy per hour capacity (because of larger diameter or stroke). Keep in mind that if the stroke changes, you must return to Step 3.. Use an ir/oil Tank. The increased surface area of the tank and piping will increase the energy per hour capacity by percent. STEP 6: If you have selected an HP, PM, SPM, TK or PRO Series model, refer to the sizing graph(s) in the appropriate series section to determine the required damping constant. If the point cannot be found in the sizing graph, you must select a larger model or choose a different series. Note that if the stroke changes, you must return to Step 3. If you have selected an adjustable model (OEM, HP or HD series), refer to the Useable djustment Setting Range graph for the chosen model. The impact velocity must fall within the limits shown on the graph. 5 Internet: STEP 1: Identify the following parameters. These must be known for all rate control calculations. Variations or additional information may be required in some cases. ) The weight of the load to be controlled (kg). B) The desired velocity of the load (m/sec). C) External (propelling) force acting on the load in (N), if any. D) The cyclic frequency at which the rate control will operate. E) Orientation of the application s motion (i.e. horizontal, vertical up, vertical down, inclined, rotary horizontal, rotary vertical up, rotary vertical down). F) The damping direction (tension [T], compression [C] or both [T and C]). G) The required stroke in (mm). NOTE: For rotary applications, please submit the application worksheet on page 81 to Enidine for sizing. STEP : Calculate the propelling force at the rate control in each direction damping is required. (See sizing examples on page 1.) CUTION: The propelling force in each direction must not exceed the maximum propelling force listed for the chosen model. If the propelling force is too high, select a larger model. STEP 3: Calculate the total energy per cycle ET = EW (tension) + EW (compression) EW = FD x S STEP 4: Calculate the total energy per hour E TC = E T x C The model selected must have an energy per hour capacity greater than this. If not, choose a model with a higher energy per hour capacity. Compare the damping direction, stroke, propelling force, and total energy per hour to the values listed in the Rate Controls Engineering Data Charts (pages 71-76). STEP 5: If you have selected a rate control, refer to the sizing graphs in the Rate Controls section to determine the required damping constant. If you have selected an adjustable model (D), refer to the Useable djustment Setting Range graph for the chosen model. The desired velocity must fall within the limits shown on the graph.

18 Installation To Ensure Correct Sizing: If shock absorbers are used at less than 5% of their maximum rated energy per cycle (less than 1% for HD and HP Series models), a smaller shock absorber should be used. If the shock absorber continually bottoms, verify sizing data. Items to Keep in Mind: Do not clamp, paint or weld the shock absorber body. Do not paint or damage the surface finish of the piston rod. Provide a Positive Stop Stop collars provide a positive stop to prevent the shock absorber from bottoming*. They also ensure that work being positioned is stopped at the same point every time. Proper stop collar mounting is as follows:. OEM Small, HP Series stop collars should be positioned to leave 1,6mm of clearance before bottoming the shock absorber. Platinum PRO and PM Series models have positive stop capabilities. However, the use of an external positive stop is recommended to extend the life of the product. B. OEM Large Series Stop collars for OEM 1.5M through OEM.M and the low profile series thread onto the shock absorber and against the center shoulder or boss. C. OEM Low Profile Series stop collar flange (SCF) serves both as a stop collar and mounting method. To install, mount SCF onto machine structure. Thread shock absorber into SCF through mounting structure until tight. Tighten set screw in flange of SCF. Check for accessibility of adjustment knob. Reorient assembly as required. Even if shock absorber is removed for maintenance, SCF maintains positive positioning and allows continued machinery operation at reduced speeds.. B. C. *Stop collars are not necessary if positive stop in mechanism already exists. Flanges with Lock Slots Flanges with lock slots, exclusively designed by Enidine, will hold the shock absorber body securely in place by applying pressure to cylinder body threads. To remove or reposition the unit, only the slotted flange bolt needs to be loosened. DO NOT REMOVE the shock absorber before this bolt is loosened. Verify that the bolt is tightened once the shock absorber is properly positioned. 13

19 Installation To Correctly djust Shock bsorber: To achieve the optimum adjustment setting: 1. Mount the shock absorber.. Set adjustment at zero ()*. Cycle mechanism; if too soft, turn adjustment to next largest number. Repeat procedure until desired damping force is obtained. 3. Lock adjustment by tightening set screw with hex key wrench provided. CUTION:. Internal damage can occur if not adjusted in gradual increments. B. If adjustment is set to the largest number and the mechanism is bottoming too hard at the end of the stroke, a larger unit is required. C. If adjustment setting is set to the lowest number and the mechanism is hitting too hard at the beginning of the stroke, a smaller unit is required. *For the approximate adjustment setting to be used, consult Useable djustment Settings section in appropriate series sections. ir/oil Tanks should be considered when:. Energy per hour exceeds maximum rating for self-contained units. B. Piston rod return sequence must be controlled. ir/oil Models, designated by the letter before the model number (Example: OEM), use air pressure over oil in a tank. n adapter (supplied with the shock absorber) is used in place of the fill plug to connect the shock absorber to the ir/oil Tank, allowing fluid to flow between them. These methods replace the coil spring in a self-contained model to facilitate piston rod return. Consult factory for maximum air pressures. ir/oil Tanks can be used with the Large OEM Series (both standard adjustable as well as custom-orificed models), and OEM Low Profile Series. Important Mounting Considerations: 1. lways mount the shock absorber with the air/oil port facing up, regardless of mounting angle.. lways position the ir/oil Tank above the shock absorber. 3. ll port and line sizes must be as large as the shock absorber port size.

Maximum damping force is achieved by turning the adjustment knob to eight (8), while minimum damping force is achieved by turning the adjustment knob to zero (). Turning the adjustment knob causes the adjustment ball to increase or decrease the clearance (orifice area) between the ball and its seat, depending on rotation direction. The internal structure of adjustable single orifice shock absorber is shown above. When a force is applied to the piston rod, the check ball is seated and the valve remains closed. Oil is forced through the orifice, creating pressure on the piston head that provides the resisting force. When the load is removed, the compressed coil spring moves to reposition the piston head and the check ball unseats, opening the valve that permits rapid fluid return. The closed cellular foam accumulator is compressed by the oil during the stroke, compensating for the fluid displaced by the piston rod during compression. Without the fluid displacement volume provided by the foam accumulator, the system would be hydraulically locked. This type of orifice design produces constant orifice area damping. Damping Type Constant orifice area damping (Dashpot) provides the largest shock force at the beginning of the stroke when the impact velocity is highest. These shock absorbers provide high-energy absorption in a small, economical design. This type of damping technology is also available in non-adjustable shock absorber models. Featuring a standard corrosion-resistant nickel-plated exterior, Enidine Platinum Series shock absorbers provide higher energy capacities than traditional shock absorbers within the same envelope size. 17 Internet: Phone: +49 () Fax: +49 ()

23 djustable Hydraulic Series Design Profiles Enidine djustable Multiple Orifice Shock bsorber djustment Knob djustment Cam Coil Spring Orifice Holes Check Ring djustment Pin Oil DJUSTBLES Foam ccumulator Piston Rod Bearing Piston Head Shock Tube Cylinder djustment Technique The adjustable multiple orifice shock absorber is similar to the principles described earlier. The check ring replaces the check ball and the adjustment feature uses an adjustment pin instead of an adjustment ball. The damping force of the shock absorber can be changed by turning the adjustment knob. Maximum damping force is achieved by turning the adjustment knob to eight (8), while minimum damping force is achieved by turning the adjustment knob to zero (). Turning the adjustment knob rotates the adjustment cam within the shock absorber. The cam, in turn, moves the adjustment pin in the shock tube, closing or opening the orifice holes. By closing the orifice holes, the total orifice area of the shock absorber is reduced, thus increasing the damping force of the shock absorber. The adjustable shock absorber enables the user to change the damping force of the unit, should input conditions change, while still maintaining a conventional-type damping curve. Damping Type Conventional damping allows linear deceleration by providing a constant shock force over the entire stroke. This standard design is the most efficient, meaning it allows the most energy to be absorbed in a given stroke while providing the lowest shock force. This type of damping can be found in both adjustable and non-adjustable shock absorbers. 18

38 Non-djustable Hydraulic Series Design Profiles Enidine Non-djustable Multiple Orifice Shock bsorber Piston Rod Foam ccumulator Orifice Holes Oil Cylinder Bearing Piston Head Check Ring Shock Tube Coil Spring Non-djustable Multiple Orifice Shock bsorber The design of a multi-orifice shock absorber features a double cylinder arrangement with space between the concentric shock tube and cylinder, and a series of orifice holes drilled down the length of the shock tube wall. During piston movement, the check ring is seated and oil is forced through the orifices in the shock tube wall, into the closed cellular foam accumulator and behind the piston head. The orifice area decreases as the piston head moves and closes the orifice holes. During repositioning, the coil spring pushes the piston rod outward. This unseats the check ring and permits the oil to flow from the accumulator and across the piston head, back into the shock tube. Multiple orifice shock absorbers can provide conventional, progressive or self-compensating damping. NON-DJUSTBLES Damping Types Conventional damping allows linear deceleration by providing a constant shock force over the entire stroke. This standard design is the most efficient, meaning it allows the most energy to be absorbed in a given stroke, while providing the lowest shock force. This type of damping is also available in adjustable shock absorbers. Progressive damping provides deceleration with a gradually increasing shock force. The initial minimal resistance at impact protects delicate loads and machinery from damage. Progressive damping shock absorbers also have built-in self-compensation, so they can operate over a wide range of weights and velocities. This type of damping provides smooth deceleration in applications where energy conditions may change. Self-compensating damping maintains acceptable deceleration with conventional type damping characteristics. Self-compensating shock absorbers operate over a wide range of weights and velocities. These shock absorbers are well suited for high drive force, low velocity applications, and where energy conditions may change. Curve shows the shock force vs. stroke curve of a self-compensating shock absorber impacted with a low velocity and high drive force. Curve B shows the shock force vs. stroke curve of a self-compensating shock absorber impacted with a high velocity and low drive force. Constant orifice area damping (Dashpot) provides the largest shock force at the beginning of the stroke when impact velocity is highest. These shock absorbers provide high-energy absorption in a small, economical design. This type of damping is also available in adjustable shock absorbers. 33

53 Heavy Duty (HD/HD) Series Design Profiles Heavy Duty Large Bore (HD/HD) Series Shock bsorbers Compact, heavy-duty design (non-adjustable shown below) safely and effectively decelerates large moving loads, with energy capacities of up to eight million in-lbs per cycle. The Enidine HD/HD Series is a large bore, multi-orifice shock absorber which incorporates a double cylinder arrangement with space between the concentric shock tube and cylinder, and a series of orifice holes drilled down the length of the shock tube wall. During piston movement, the check ring is seated and oil is forced through the orifices in the shock tube wall, into the gas charged bladder/accumulator area, and behind the piston head. The orifice area decreases as the piston moves and closes the orifice holes. The bladder/accumulator is also compressed by the oil during the compression stroke, which compensates for the fluid displaced by the piston rod during compression. During repositioning, the pressure from the bladder/ accumulator pushes the piston rod outward. This unseats the check ring and permits the oil to flow rapidly through the piston head into the front of the shock tube. The unique gas charged bladder accumulator replaces mechanical return springs, decreasing overall product size and weight. The HD/HD Series can provide conventional, progressive or self-compensating damping. HD SERIES Piston Rod Bearing Fill Plug Gas Charge Valve Oil Bladder ccumulator Shock Tube Check Ring Piston Head Orifice Holes Cylinder HD/HD Series Shock bsorber Sizing 1. Determine load weight (kg), impact velocity (m/sec), propelling force (N) if any, cycles per hour and stroke (mm) required.. Calculate total energy per cycle (Nm/c) and total energy per hour (Nm/hr).

69 Heavy Industry (HI) Series H Series Heavy Industry (H ) Series Buffers Enidine s Heavy Industry Series (HI) buffers safely protect heavy machinery and equipment during the transfer of materials and movement of products. The large-bore, high-capacity buffers are individually designed to decelerate moving loads under various conditions and in compliance with industry mandated safety standards. Control of bridge cranes, trolley platforms, large container transfer and transportation safety stops are typical installation examples. Industry-proven design technologies, coupled with the experience of a globally installed product base, ensure deliverable performance that exceeds customer expectations. Prior to HI Series buffer manufacture, computer-simulated response curves are generated to model actual conditions, verify product performance, confirm damping characteristics and generate unique custom-orificed designs that accommodate multi-condition or specific damping requirements. Characteristics of the HI Series include a nitrogen-charged return system that allows for soft deceleration and positive return in a maintenance-free package. The oversize bore area results in optimal energy absorption capabilities and increased internal safety factors. State-of-the-art testing facilities ensure integrity of design and product performance. Piston Cap Piston Rod Separating Piston Oil Reservoir Cylinder Orifice Oil Chamber HI SERIES Design Overview The HI Series buffer design incorporates the proven damping system of multiple orifice patterns drilled down the shock tube length, for precise deceleration profiles, coupled with a nitrogen return system for controlled extension of the piston rod to its original position. During piston movement, oil is forced through the orifice pattern into the oil reservoir chamber. This controlled movement of a piston head by decreasing the orifice area results in precise decay of impact velocity and safe deceleration of the moving load. The oil volume evacuated from the high pressure chamber moves the separating piston, compensating for the oil differential within the unit. Extension of the piston rod for the next impact is accomplished by the force created from the compressed nitrogen chamber, which acts as both a oil volume compensator, and return force mechanism. The pressure created pushes the fluid back into the oil chamber and creates a force to reposition the piston rod to the fully extended position, ready for the next impact sequence. The nitrogen return system enables the HI Series to be designed for the maximum energy absorption within the smallest envelope size. 64

74 ShockCover5-B-4-English /6/4 1:54 M Page 69 Rate Controls E The advantages of using rate controls include: 1. Longer Machine Life The use of rate controls significantly reduces shock and vibration to machinery caused by uncontrolled machine operation. This further reduces machinery damage, downtime and maintenance cost, while increasing machine life.. Improved Production Quality Harmful effects of uncontrolled motion, such as noise, vibration and damaging impacts, are moderated or eliminated so that production quality is improved. 3. Safer Machinery Operation Rate controls protect machinery and equipment operators by offering predictable, reliable and controlled machine operation. 4. Competitive dvantage Machines and end products become more valuable because of increased productivity, longer life, lower maintenance and safer operation. Enidine offers a wide range of rate controls that provide motion control in tension, compression, or both directions. djustable and non-adjustable tamperproof models are available to fit your particular application requirements. The resisting force provided by Enidine rate controls is typically constant over the entire stroke when the piston rod is moved at a constant velocity, since the rate controls are single orifice products. D Series models (see page 76) can be custom VELOCITY nidine Rate Controls are used to regulate the speed or time required for a mechanism to move from one position to another. They use proven technology to enhance performance in a variety of product applications. Rate controls are typically used to control pneumatic cylinders, linear slides, lids, and other moving mechanisms. VELOCITY Design Profiles STROKE SINGLE ORIFICE RTE CONTROL CONSTNT FORCE FORCE OPERTION STROKE MULTIPLE ORIFICE RTE CONTROL FORCE OPERTION CONSTNT FORCE orificed to provide increasing resisting force over the stroke through the use of multiple orifices in the shock tube. This can be beneficial when controlling the velocity of a lid as it closes, since the torque from the weight of the lid changes as it closes. Rate Control djustment Techniques properly adjusted rate control safely controls machinery operation, and reduces noise levels from uncontrolled motion. To correctly adjust the rate control after it has been properly sized for the application, set the adjustment knob (per the useable adjustment setting graphs on pages 7 and 75) for the applicable model. Cycle the mechanism and observe the motion of the system. If the motion of the mechanism is too fast, move the adjustment dial to the next largest number until the desired velocity is achieved. If the motion of the mechanism is too slow, move the adjustment dial to the next smallest number until the desired velocity is achieved. RTE CONTROLS Selecting the Proper Enidine Rate Control When sizing a rate control, determine the velocity and drive force at the rate control. Do not bottom the rate control in tension or compression. Provide an external positive stop. Environment (ambient temperature, corrosive conditions, etc.) must be considered. When both tension and compression rate control are required, select an D or D model, which can accommodate your specific application requirement. For hard-to-reach applications which require adjustment, a remote adjustment cable is available with the D 5M Series. Internet: Phone: +49 () Fax: +49 ()

75 djustable, Double cting (D Series) Rate Controls Enidine Double cting djustable (D) rate controls control the velocity of both linear and rotational loads throughout their entire motion. djustment cartridges on the D 5M Series allow flexibility in controlling the speed for an applied force in both tension and compression directions. Maximum damping is achieved by turning the adjustment knob to the number eight (8) setting, while turning the knob to the zero () setting provides minimal resistance. Interchangeable, threaded, fixed-orifice cartridges can provide consistent, tamper-resistant damping to meet particular application requirements. The D 5M Series utilizes two independent adjustment cartridges for motion control in each direction, housed in the cylinder end. The D 7M Series has independently controlled tension and compression capabilities located at each end of the unit. Compression djustment Cartridge Shock Tube Foam ccumulator Cylinder Rate Controls Design Profiles Resistance is controlled by using a wrench key at either end of the rate control and adjusting the movement by following the stiffer (+) or softer (-) indications. When the rate control is compressed, the oil is orificed through the compression adjustment cartridge and flows freely through the tension adjustment cartridge. The tension cartridge check ball unseats and allows free flow of the oil to the rod end of the shock tube. foam accumulator is utilized to accept the volume of oil displaced by the piston rod. When the rate control is extended, oil is moved through an internal flow path in the shock tube and is orificed through the tension adjustment cartridge. The compression cartridge check ball unseats and allows free flow of the oil into the blind end of the shock tube. Tension djustment Cartridge Orifice Piston Clevis Bearing Oil Piston Rod Piston Head Cylinder End Check Ball Non-djustable, Double cting (D Series) Rate Controls D Series rate controls are ideally suited for high-energy, heavy load applications requiring rate control in tension, compression or both directions. These non-adjustable, custom-orificed units are designed to specific input conditions, and allow for single and multiple orifice configurations. Upon compression of the rate control, the compression check ball seats. s the piston head moves, oil is forced through the orifice hole(s) located in the shock tube, producing the required damping force. fter the oil has passed through the orifice hole(s), a portion of the oil passes through the extension check valve and fills the rod end of the shock tube. The remainder of the oil volume displaced by the piston rod compresses the foam accumulator. Upon extension of the rate control, the extension check ball seats. s the piston head moves, oil is forced through the orifice hole(s) located in the shock tube producing the required damping force. The compression check ball is unseated by the flow of oil which fills the blind end of the shock tube.
