Abstract (en)

The pump or motor has a rotor (10) seated on a drive shaft (12) eccentrically mounted in a rotor chamber (14) with an inlet and an outlet with its end surfaces tight against the chamber end walls. Radial rotor vanes (30) at intervals interact in a sealed manner with the peripheral surface of the chamber. The rotor chamber is arranged inside a stator (16) radially adjustably mounted in the bearing housing (20). An annular guide path (54) between the rotor and at least one end surface of the rotor chamber engages the vanes and holds them in a radial position sealed wrt. the chamber's inner peripheral surface.
