A gerotor pump having an inner rotor and an outer rotor, which is also the rotor of an electric drive, having a housing and a flange which closes the housing with the motor compartment, the rotor being arranged on a shaft and sealing against the flange at a gap, wherein, in addition to the gap, there is at least one device with which at least a partial pressure compensation takes place between the suction region of the gerotor pump and the motor compartment of the gerotor pump.

Gerotor pump with pressure equalization

Gerotor pump comprising an inner gerotor and an outer gerotor and an electric motor in a pump housing, and the outer gerotor is formed integrally with the rotor of the electric motor, wherein magnets are integrated into the outer gerotor, and the rotor is rotatably mounted on a shaft that is fixed on one side to a housing or a housing base of the pump housing.

Gerotor pump and method of making pressure equalization in a gerotor pump

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.

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 vane pump including a rotor, which is arranged within a cam ring located in the pump housing, and which carries a plurality of radially displaceable vanes which are also displaceable along the inner double-symmetrical contour of the cam ring, with the inner contour defining two diametrically opposite pump chambers and with each chamber being divided in three sections forming, respectively, a suction region, a pressure region, and a separation region between the suction and pressure regions.
