ROTARY PISTON ENGINE OF INTERNAL COMBUSTION (VERSIONS) Russian patent published in 2013 - IPC F02B57/04 F01B13/04 

FIELD: machine building.

SUBSTANCE: rotary piston engine of internal combustion includes immovable casing, bearing surface and rotor with cylinders. Bearing surface is fixed on the casing. Rotor is capable of rotation relatively the casing. The cylinders are part of rotor and are fixed centrally symmetrically relatively rotor rotation axis. In each cylinder there is a piston equipped with piston rod and supporting roller with lever of supporting roller. Supporting roller interacts with curved supporting surface mounted on the casing. On rotor flywheel there pivoted is a double-arm lever (balancing lever) that is capable of rotation relatively the rotor. The ends of double-arm lever (balancing lever) are connected to the levers of supporting rollers of opposite cylinders by movable pivots via rods. In channels for operating fluid input-output into the operating cylinders there installed are the valves that open at the beginning of output stoke and close at the end of the input stroke according to the phases of each operating cylinder.

EFFECT: increase of revolutions upper limit, simplification of rotor balancing and increase of engine efficiency.
