ABSTRACT:
A radial piston pump includes an axially slidable rotor which is rotatably connected to a connected shaft through a spring clutch engaging one end face of the rotor. The rotor is located in a housing or in the stator so as to constitute a frontal gap between the rotor and the housing or stator on the pressure side of the machine, through which frontal gap, during operation of the device, pressure fluid of the pressure side is permitted to be supplied to at least one sector area of that end face of the rotor opposite the spring clutch. This causes centering of the rotor by the spring clutch and by the pressure of the pressure side in such a manner that no metallic contacts occur in an axial direction and, thus, no friction losses.
