1 4 Motion Control Industrial Gas Springs Pull Type Takes over when things get too tight for gas pressure springs If ACE gas push type springs cannot be used due to a lack of space, ACE s industrial gas pull type springs come into their own. The compact assistants with body diameters of to 40 are effective in the direction of traction and work in the opposite way to the principle of gas push type springs. This means that the gas pressure in the cylinder draws the piston rod in and, when closing a fl ap for example, supports the manual force with the pressure springs. ACE s gas pull type springs are also self-contained, maintenance-free machine elements and equipped with a standard valve to individually regulate the gas pressure, whereby they cover forces between and 5,000. Any installation position, extensive DI standardised accessories and various models enable universal use.

2 Product Families Overview 5 Function of a Gas Spring Pull Type Gas pull type springs work based on the reverse principle of a gas push type spring. They are also individually fi lled according to customer request to a certain pressure (extension force F 1 ). However, the piston rod here is pulled inwards by the gas pressure in the cylinder. The higher the pressure, the greater the extension force. The piston ring surface between the piston rod and the inner tube is decisive for the function. When the piston rod pulls out, the nitrogen from the piston is compressed in the inner tube. The force increase (progression) of the gas spring is due to the rising pressure. The force increase is almost linear. Calculation Principles Force- Characteristics of Traction Gas Spring (Pull Type) Free calculation service see page! 5 F 4 F 2 Outward Inward Total F 1 F 3 5 F R F 1 = nominal force at C (this is the pressure figure normally used when specifying the gas spring) F 2 = force in the complete extended position When extending the piston rod, there is an additional friction force caused by the contact pressure of the seals (this only occurs during the extension stroke): F 3 = force at the beginning of the extension stroke F 4 = force at the end of the extension stroke Gas Springs (Pull Type) Type Progression approx. % 1 Friction F R approx. in GZ GZ GZ GZ Depending on the fi lling force 2 Depending on the stroke Progression: (the slope of the force line in the diagram above) is due to the reduction of the internal gas volume as the piston rod moves from its initial position to its fully stroked position. The approx. progression values given above for standard springs can be altered on request. Effect of termperature: The nominal F 1 fi gure is given at C. An increase of C will increase force by 3.4 %. Filling tolerances: to +40 or 5 % to 7 %. Depending on size and extension force the tolerances can differ.

3 Industrial Gas Springs Pull Type Valve Technology GZ- to GZ-40 Industrial Gas Springs Pull Type Very low progression rate The solution to a lack of space: If standard push type gas springs cannot be used due to a lack of space, ACES industrial pull type gas springs come into their own. They work in the opposite way to standard push type gas springs. The piston rod is retracted when the cylinder is unloaded. The gas pressure in the cylinder draws the piston rod in. ACE pull type gas springs offer the maximum service life thanks to the solid chrome-plated piston rod and an integrated sliding bearing. The maintenance-free and ready-to-install products are available in body diameters of to 40 as well as forces from 40 to 5,000 and are available from stock with valve and large selection of accessories. The traction force can be subsequently adjusted using the valve. Gas traction springs from ACE are used in industrial applications, especially in mechanical engineering and in medical technology as well as in the electronics and furniture industries.
