ROTARY PISTON ENGINE Russian patent published in 2018 - IPC F02B55/00 F01C1/39 

FIELD: motors and pumps.

SUBSTANCE: invention relates to rotary pistons engines. Gist of the invention consists in that the engine comprises a stator, end caps (front and rear) comprising supports of a rotating crankshaft and rotor stops, movable rotor, performing a circular parallel motion, movable cylindrical hinges with grooves, movable blades. Rotor is installed eccentrically on the crankshaft. Blades are hingedly fixed in the cylindrical grooves of the stator and perform simultaneous rocking motion with respect to the stator and translational movement in the hinges grooves. Hinges are mounted movably in the cylindrical holes of the rotor. Processes of suction, compression, combustion of fuel mixture, expansion and release of combustion products occur in the working chambers formed by the inner surface of the stator, the outer surface of the rotor, the surfaces of the blades and end caps. Change in the volume of the working chambers occurs with a circular parallel motion of the rotor. Circular parallel motion of the rotor is provided by a reducer containing a fixed central gear fixed in the end cap, gears rotating on the axles fixed on the driver-cranked shaft, gear wheel, and having gear ratio between the central gear and the rotor gear, equal to the value minus one.

EFFECT: reduction in the vibration level due to the equality of all the engine chambers, both in volume and shape.
