Description
The basic elements ot the QX internal gear pumpare the pinion, the internal gear and the gearhousing. Including the drive shaft there are onlythree moving parts. Pressure ranges 3 and 4 have2 and 3 gear sets respectivelyTandem and multiple pumps mean that there areover 1000 possible variations available.

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 aresingle direction rotation and cannot be driven inreverse. Internal leakage oil is fed internally to the low pressure side.

Gerotor Motors
Without drain lineIntegrated speed sensorIntegrated valvesParking brake or wheel hubOutput torques from 115 up to 3900 NmDisplacements from 52 to 2095 cc/revWorking 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 leakagebetween 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 apower stroke. The oil pushes the pistons radiallyoutwards, so that the cam cylinders attached tothe pistons press against the cam ring which isfirmly 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 powerstroke the rotating oil distributor closes the inletopening and opens the outlet. The piston is thenpushed back through the cam in the cylinder andthe oil flows away through the return piping. The change in rotational direction of the motor iscarried out by changing over the inlet flow direction. This can also be done during operationand without stopping.

System description
The L.8S valve range represents a flexible unitconstruction, the elements of which, according torequirements and application, may be combined inone valve unit. A typical valve unit working with aconstant flow pump contains a three-way pressurecompensator directional control valves and therequired end plate. The pump may be attached tothe unit by any hydraulic connection.With all of the directional valves in the neutralposition the three way compensator unloads totalinput flow to tank at virtually no pressure drop.When one of the directional control valves isactuated the consumer pressure is transmitted tothe three-way pressure level via the control channel. This maintains the pressure drop between the pressure- and control gallery insidethe unit, so that the flow to the consumer isalways constant irrespective of load.A simple control element permits selective engagemant combined with a constant or LSpump.

These proportional valves control the rate of flow tothe receiver irrespective of load, because there is a 2-way pressure compensator integrated into eachdirectional control valve. In addition each directionalvalve contains pressure relief functions individuallyadjustable for each receiver. The valve system comprises 2 to 9 single sections,held together by tie bolts. A pump inlet section, 1 to 7direction valves and an end section form the valvebank. All proportional directional control valves have internalload signals for the accompanying 2-way pressurecompensator. The highest load pressure signal is conducted via check valves to the pump inlet section.

These monoblock construction valves control flow tothe receiver irrespective of load. All principle functions of the valve are integrated inone compact unit. They consist of the pump inlet section with pressure compensation and up to fourproportional directional control valve sections. Byusing internal pressure signals selected directionalcontrol valves proportionally control flow irrespectiveof load.All directional control valves may be operate simultaneously, but only the flow rate of the receiverwith the highest pressure is controllable irrespectiveof load.The methods of operation available - manual, hydraulic, electric or any desired combination - andthe options with the different pump connection sections with pressure compensation in 2- or 3-wayoperation or pressure valve - offer a wide scope ofapplications relief.

Directional Valves – Miscellaneous
Pmax Series and brief description Symbol
Two-stage Spool ValvesThe «High-Performance Spool Valve» Principle. The main spool (2)contains within it a small 5 mm dia. pilot spool (3). This combination ofdirect and pilot actuation produces a self-regulating hydraulic amplifi-cation of the spool actuating force, in both the offset and recenteringdirections. The pressure existing at P is directed by the pilot spool to oneor other end of the main spool, thus producing a hydraulic force whichassists either the solenoid or return spring, as appropriate.This force amplification means that the High Performance Spool Valveis largely unaffected by Flow rate, asymmetry of flow paths, long periodsof energisation, high viscosities or very large pressure drops. It is ideallysuited to all applications which require extremely high reliability ofON- and OFF switching. Also, in many situations an High PerformanceSpool Valve can be «designed in» in place of a much larger valve.
Adapter- and Subplates, and Accessories. For modular stackingassemblies (horizontal or conventional vertical stacks) we offer a widerange of both industry standard components in ISO Sizes 2, 3, 5, 7 andspecial components covering the same flow ranges. On request, we cancombine these with the required valves to build complete, compact,functioning assemblies.

LRS is a power-reducing DIN plug for theranges 15–55V DC and 100–250 V DC. Atthe moment of switch-on, the full power(max. 40 W) is applied to the valve andshortly afterwards this is reduced to a pre-adjusted level eg. 10W. Modern electronictechniques allow this to be done without thepower-drop being dissipated as heat. Uses:power savings; limiting coil temperaturerise; permit deliberate but transient over-current condition.

General description
– prevents a hydraulic actuator from running ahead of the available oil supply in the event of external driving forces i.e. negative, or over-running loads
– takes over the load control-, load holding- and safety functions– provides leak-free load holding in the neutral position– for sensitive control and precision movement of actuators under load– mounted directly on the hydraulic cylinder for the highest security against unintentional movements– for controlling the speed of hydraulic cylinders and motors, for example on cranes, lifting platforms, etc.
Advantages of the Cindy load control valve
– absolutely zero-leakage load holding– 420 bar working pressure with 3-fold safety– pilot operated load-control valve and bypass check valve both combined in one axis– Load does not accelerate in the event of a hose burst(with back pressure-independent models)– the opening action is almost entirely independent of the load pressure (area ratio 1:113)– above 100 bar load pressure, it controls like a compensated 2-way flow controller (patented follower principle)– fully compensated pressure relief valve opens independently of tank- or return line back-pressure– over-compensated models are available with various reducing stages – outstanding fine control from optimised, low-flow control notches– high resolution, thanks to the long control stroke– the valve is guaranteed to close, even with a broken spring– hardened, ground and lapped seat valve omponents ensure permanent leaktightness and long service life– low-noise operation thanks to multiple, specially shaped notches– very low hysteresis– various pilot pressure ranges can be chosen– various types of pilot-control are available– damping properties guarantee a stable system even in sensitive applications– additional asymmetric damping properties can be provided– high power density– wide choice of build types can be supplied

Leakfree (excavator) pipe rupture valve
Prevents uncontrolled movement of the cylinder if a pipe or a hose burst occurs
ESVleakfree excavator pipe rupture valve
– flanged directly into the cylinder withan SAE flange, trouble-free originalequipping or retro-fitting
– no more preassembling thanks to fit-ting of unions on ports A, E, L and X
– the pressure relief valve operatesindependent of the return pressurein port A
– no need for a reservoir line with alarge nominal diameter
– the housing dimensions are identi-cal for both sizes of port (3/4" and1"), which makes it easier to run thepipework when using different typesof machine
RS/RSE/RSG/RSW/RSPRPipe rupture valve
– either almost leakfree closing orslow lowering
– minimal spatial requirement thanksto compact design
– simple adjustment of flow rates
