ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02B55/02 F02B55/14 F01C1/356 

FIELD: engines and pumps.

SUBSTANCE: rotary-piston internal combustion engine E1 includes outlet shaft 1, rotor, housing 4, annular working chamber 5, inlet hole 11, outlet hole 12 and fuel injector 14. Annular working chamber 5 is formed by means of rotor and housing for formation of inlet working chamber, compression working chamber, working combustion chamber and outlet working chamber. Element for creation of pressure/element under pressure is provided on rotor for partitioning of annular working chamber. Back-and-forth partitioning elements 7, 8 are provided in housing for partitioning of annular working chamber. Shifting device is provided to shift back-and-forth partitioning element in the direction of extended position. Element for creation of pressure/element under pressure includes arc-shaped partitioning element 6 which has the first and the second inclined surfaces and front sliding surface. Back-and-forth partitioning element has the first and the second sliding surfaces creating the contact with the first and the second inclined surfaces of arc-shaped partitioning element 6, and the front sliding surface.

EFFECT: smaller sizes and higher efficiency of engine.
