ABSTRACT:
The invention relates to a gerotor type of rotary piston machine. In this type of device an externally toothed rotor member is eccentrically offset relative to an internally toothed stator member and in operation these members mesh to form expanding and contracting cells on opposite sides of the line of eccentricity. There is a shaft means for driving the rotor and a distributing valve for feeding and exhausting the cells. The distributing valve, which is normally connected to the drive shaft, is connected to the rotor member for movement therewith adjacent to the rotor and stator member. An annular chamber is formed between the periphery of the distributing valve and the interior of the casing. One set of the distributing ports is formed as ports within the confines of the periphery of the valve. The other set of distributing ports are formed by the periphery of the valve.
