swash plate providing the lifting impetus. An axial bearing absorbs the piston forces. Swash plate pumps are occasionally used in mobile hydraulics and vehicle hydraulics.

Electrical drive motor for pumps, which is installed beneath oil in the tank and therefore does not require a closed housing or whose housing also performs the tank function, particularly in the case of

Pressure at the inlet to a device or a system (DIN 24 312). Self-priming pumps generate a negative pressure during priming if the fluid feed height is not positive. Min. and max. inlet pressure are dependent

comparatively infrequently. Axial piston machines have a smaller output volume than radial piston pumps and also have simpler sliding-contact and sealing conditions at the control disc (automatically adjusting [...] radial piston pump. Today they therefore cover roughly 80 % of the demand for high-pressure piston pumps.

valves have to be used (storage losses). Accumulator drives are equipped with constant pumps or variable pumps with a pressure controller . They become more cost-effective as more consumers are supplied

the suction chamber can be increased in size. At pressures of around 150 to 200 bar special gear pumps still have good efficiency , however they then become very noisy.

or high response proportional valves are used (Figure D 46) . In a hydraulic system with constant pumps the flow rate not required Q V (Q V = Q 1 – Q N) is fed back to the tank (Figure D 47) . The power [...] throttle is used relatively frequently, this situation is because it is relatively cheap (constant pumps) and because it has a very high dynamic performance (up to a few hundred Hz for control with throttle

accuracy is around ±3-5 %. Alternative: rotary flow divider , multiple pump . In the case of multiple pumps, the volumetric flow is fed to multiple displacers, which are coupled mechanically and divide the

Interaction of one or more pumps (primary element) with one or more (secondary element, in most cases a hydraulic motor). The distance between the two devices is of no significance (open transmission)

Feature on hydraulic pumps of piston and vane design that changes the delivery flow in accordance with an input variable. On the pump this is a distance s that can be specified in various ways (Figure
