The proposed power unit of the rotary-piston type, for example an internal combustion engine, compressor or pump, has a stator (8) and a rotor (3) designed in such a way as to allow a number of variable-volume working chambers to be created in the stator when the rotor turns. The meshing mechanism (13, 14) between the stator and the rotary piston which rotates on an eccentric section (2) of the shaft (1) is essential for the management of that rotation and is situated outside the rotary piston. For that purpose an aperture (15) is provided in the wall (11) of the stator and is shut off by a rotating disk (or ring) (16) through which a spigot (4) passes and rigidly connects the rotary piston and a pinion (13). This arrangement creates a power unit with a triangular stator and double-peak rotor. Several sets of balance, lamellate, spring-loaded sealing elements are mounted on the lateral surface of the stator. They are in contact with the side surface (7) of the rotary piston which has a forced cooling system. <IMAGE> |
