The invention relates to a radial piston pump, comprising an inlet chamber with an inlet connection, an eccentric which may be driven in a rotating manner, arranged within the inlet chamber, for driving at least one piston of the radial piston pump, a cylinder bore for guiding the piston and an inlet controller, which opens and closes a connection between the inlet chamber and the cylinder bore, depending on the piston position. The radial piston pump is characterized by at least one balancing element ( ) for the eccentric ( ), which rotates synchronously with the eccentric ( ) in the inlet chamber ( ), the balancing element ( ) being so arranged in the inlet chamber ( ) and/or so formed in its contour that a hydraulic resistance is formed between the inlet connection ( &prime;) and inlet controller ( ), or the flow of medium reaching the inlet controller ( ) is unaffected.

Radial piston pump

The invention relates to a valve arrangement with a pressure limiting valve and a flow regulator valve, which comprises a flow regulator piston, having at least one first hydraulic resistor, distinguished in that the flow regulator valve's ( ) flow regulator piston ( ) has a split pressure return surface and in that the first part (ring surface ( )) of the pressure return surface is capable of working at a pressure p and a second part (annulus surface ( )) of the pressure return surface is capable of working at a pressure p

Valve arrangement and pump for a gear system

The invention relates to a valve arrangement with a pressure limiting valve and a flow regulator valve, which comprises a flow regulator piston, having at least one first hydraulic resistor, distinguished in that the flow regulator valve's (,) flow regulator piston (,) has a split pressure return surface and in that the first part (ring surface (,)) of the pressure return surface is capable of working at a pressure p,and a second part (annulus surface (,)) of the pressure return surface is capable of working at a pressure p

A suction-throttled pump, comprising at least one displacement body for the delivery of a medium and movable in a delivery chamber, into which opens at least one inflow channel extending between the delivery chamber and a suction chamber, and comprising a suction control valve, the pump being characterised in that the suction control valve (,&Prime;) co-operates directly with the inflow channel (,&prime;) and is arranged at the end thereof facing the suction chamber (,).
