ABSTRACT:
The rotary piston machine contains a rotor (22) having a plurality of sector-shaped chambers (30). Each chamber (30) houses a flap piston being swivelingly mounted and reciprocated synchroneously with the rotation of the rotor (22). By each of the double acting flap pistons (32) two working compartments are confined, and always two adjacent flap pistons (32) are driven in counterphase to one another. The adjoining working compartments of adjacent piston chambers (30) are commonly connected to inlet and outlet aperture slots (44) in the periphery of the rotor (22). The inlet and outlet ports (42) and ducts (A,B,C,D,E) are provided in the stator (21) around the periphery of the rotor (22).
