Description Gear motors are dimensionally the same as the corresponding pumps and in operation provide the opposite function to the pumps. (However it is not possible to convert a pump into a motor.) Due to the internal seal layout these motors are single direction rotation and cannot be driven in reverse.

Gerotor Motors Without drain line Integrated speed sensor Integrated valves Parking brake or wheel hub Output torques from 115 up to 3900 Nm Displacements from 52 to 2095 cc/rev Working pressures up to 315 bar Description Gerotor motors are slow speed/high torque motors. The power element of this motor is the rotor unit, comprising rotor, outer ring (stator) and 7 cylinders. (BMP has 6 cylinders.) The patented rotor profile prevents direct leakage between the pressure chambers, resulting in negligible internal leakage and volumetric efficiency.

Description The hydraulic oil from the inlet is fed over the distributor plate to the pistons, which execute a power stroke. The oil pushes the pistons radially outwards, so that the cam cylinders attached to the pistons press against the cam ring which is firmly attached to the motor housing, thereby forcing the motor housing, as well as the oil distributor, to rotate. As soon as the piston reaches the end of its power stroke the rotating oil distributor closes the inlet opening and opens the outlet. The piston is then pushed back through the cam in the cylinder and the oil flows away through the return piping. The change in rotational direction of the motor is carried out by changing over the inlet flow direction. This can also be done during operation and without stopping.

System description The L.8S valve range represents a flexible unit construction, the elements of which, according to requirements and application, may be combined in one valve unit. A typical valve unit working with a constant flow pump contains a three-way pressure compensator directional control valves and the required end plate. The pump may be attached to the unit by any hydraulic connection. With all of the directional valves in the neutral position the three way compensator unloads total input flow to tank at virtually no pressure drop. When one of the directional control valves is actuated the consumer pressure is transmitted to the three-way pressure level via the control channel. This maintains the pressure drop between the pressure- and control gallery inside the unit, so that the flow to the consumer is always constant irrespective of load. A simple control element permits selective engagemant combined with a constant or LS pump.

Application controlling 2 axles in 4 steering modes: front only; rear only; both circular; both crab.

For modular stacking assemblies (horizontal or conventional vertical stacks) we offer a wide range of both industry standard components in ISO Sizes 2, 3, 5, 7 and special components covering the same flow ranges. On request, we can combine these with the required valves to build complete, compact, functioning assemblies. Two-stage Spool Valves The «High-Performance Spool Valve» Principle. The main spool (2) contains within it a small 5 mm dia. pilot spool (3). This combination of direct and pilot actuation produces a self-regulating hydraulic amplification of the spool actuating force, in both the offset and recentering directions. The pressure existing at P is directed by the pilot spool to one or other end of the main spool, thus producing a hydraulic force which assists either the solenoid or return spring, as appropriate. This force amplification means that the High Performance Spool Valve is largely unaffected by Flow rate, asymmetry of flow paths, long periods of energisation, high viscosities or very large pressure drops. It is ideally suited to all applications which require extremely high reliability of ON- and OFF switching. Also, in many situations an High Performance Spool Valve can be «designed in» in place of a much larger valve. 31

Flow Measurement Devices and Electronic Amplifiers Nom Size Flow rate l/min P max Series and brief description Symbol 10 1-60 315 (420) 16 4-150 QSB extremely compact, bi-directional flow meters based on a patented «Disc» principle. Available in HTF cartridge forms (DC), DD and DE. On-board electronics produce an analogue proportional signal in the range ± 6 Volt. Changes in flow rate are signalled within milli-seconds therefore this unit is well suited to closedloop control systems. EQP-01 are digital display meters for the above QSB units. The analogue input is converted to a 3 -digit ± LED display. SAN-135 is a single-channel PWM DC amplifier with ramps. SAN-227 is a 2-channel PWM amplifier with ramps. All models are designed for proportional valve control, and are supplied in Eurocard form. PBS-3A is a compact and low-cost, single channel, PWM amplifier for controlling Proportional Valves. A potentiometer knob and scale-plate are situated on the front cover. Stable, robust, adjustment. Internal pot. for I min /I max settings. Full scale (270 ) control always available. LRS is a power-reducing DIN plug for the ranges 15 55V DC and 100 250 V DC. At the moment of switch-on, the full power (max. 40 W) is applied to the valve and shortly afterwards this is reduced to a preadjusted level eg. 10 W. Modern electronic techniques allow this to be done without the power-drop being dissipated as heat. Uses: power savings; limiting coil temperature rise; permit deliberate but transient overcurrent condition.
