ABSTRACT:
In a rotary radial piston machine substantially axially extending passages are provided extending from the respective cylinders in axial direction through the rotor for directing the flow of fluid into and out of the rotor. A control body has entrance and exit passages and is located at least at one end of the rotor, and means are provided for obtaining a suitable clearance between a rotary control face of the rotor and a stationary control face of the stationary control body preferably including annular balancing chambers whose pressures act in axial direction on a sleeve guided on the rotor shaft and having an end abutting the control body.
