ROTARY ENGINE Russian patent published in 2009 - IPC F02B53/08 F01C1/22 F01C17/06 

FIELD: engines and pumps.

SUBSTANCE: invention relates to internal combustion engines. Proposed rotary engine comprises housing with outlet opening and working chamber, two-apex rotor with larger and smaller axes of symmetry fitted on eccentric shaft, and pump with intake hole. Said pump is arranged coaxially with rotary engine on eccentric shaft and comprises two-apex rotor. Housing chamber and pump working surface outlines comply with circumference conchoids. Engine and pump shafts are interjointed in synchronism. Combustion chamber is arranged between engine and pump housings and accommodates branch pipe on engine housing and branch pipe fitted on pump housing. The former houses piston-type valve, while the latter accommodates spring-loaded plate valve. Valve stems of both valves are interjointed in synchronism. Two-apex rotors of engine end pump have slots made along rotor larger axis of symmetry. Width of slots equals diametre of pins fitted at the conchoids pole. Pump intake hole is made in pump housing working surface, to the right of housing axis of symmetry. Intake hole top edge is aligned with pump rotor apex, with rotor in TDC. Discharge hole is made in engine working surface, to the left of housing axis of symmetry. Anti-vacuum valve is arranged on engine working surface, to the right of engine axis of symmetry.

EFFECT: higher efficiency.
