Abstract
A gerotor pump including a housing which includes a first supply socket and a second supply socket, an inner rotor, and an outer rotor rotatably located relative the housing. The inner rotor is located within the outer rotor, lobes of the inner and the outer rotors are engaged, and the inner rotor is centered around a rotational axis which is eccentric from an axis of rotation of the outer rotor. A pressure chamber with a high pressure and a low pressure section is defined between the inner and outer rotors. The inner rotor is rotatably arranged on a shaft cylinder which is fixed at one end of a central drive shaft of the pump and is centered about the rotational axis, whereby the inner rotor wanders in the outer rotor when the central drive shaft is turned. The inner rotor is provided with radial supply conduits extending from the pressure chambers to the shaft cylinder. The shaft cylinder is provided with at least a first and a second cylinder opening, such that the first cylinder opening is axially displaced relative the second cylinder opening, and the first opening is arranged such that it is connected to the high pressure section, and the second cylinder opening is arranged s…
