FIELD: combustion engine. SUBSTANCE: rotary engine has fixed hollow body with inner elliptical space, rotor-piston installed for rotation in body in line with working space. Rotor has flat surface and tangentially arranged slots with volume shutoff cams fitted in slots and spring-loaded in direction of rotor rotation. Volume shutoff cams are installed for pressing the apex to body working surface and for provision of variable contact with surface. Apex of each cam has projection at side opposite to direction of rotor rotation. Projection has flat and convex surfaces. Curvature of convex surface is greater than curvature of body surface. Flat surfaces of rotor and cam projection are arranged at angle to each other. Cans are arranged on periphery of rotor. EFFECT: enlarged operating capabilities. 5 dwg
