SHATROV ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02B57/00 F01B13/04 

FIELD: engines and pumps.

SUBSTANCE: rotary piston internal combustion engine includes stationary housing 1 with rotor 2 located in it and operating cylinders 3. Piston 4 equipped with piston-rod 5 and support roller 6 is arranged in each of operating cylinders 3. Support roller 6 interacts with curved support surface 7 installed on housing 1. Number of operating cylinders 3 is even. Operating cylinders 3 of rotor 2 are offset in rotation plane of rotor 2 from rotation centre of rotor 2 through equal distance. Operating cylinder 3 opposite lying to each operating cylinder relative to rotation centre of rotor 2 is located centrally and symmetrically and their axes are parallel. For each pair of opposite lying operating cylinders 3 there installed are two levers 8 and one rod 9. Levers 8 are fixed on rotor 2 with fixed hinges 10. Each lever 8 is connected by means of one movable hinge 11 to piston-rod 5 of the appropriate operating cylinder 3, and by means of the other movable hinge 11 through rod 9 to lever 8 of opposite lying operating cylinder 3.

EFFECT: simplifying the manufacture and service, as well as increasing efficiency of the engine.
