ROTARY ENGINE Russian patent published in 1997 - IPC

FIELD: power-plant engineering. SUBSTANCE: engine has compression stage air collector and working stage exhaust pipe communicating, respectively, with compression chambers and expansion chambers through ports made in stators, fuel feed pipe running to compression chamber, gears mounted on rotor half-axles which are in mesh with each other, valve in fuel feed pipe one of whose ends communicates with fuel pump and other end carries injector placed in gas conduit, electric transducer installed in expansion chamber, door in gas conduit that closes port through which compression chamber communicates with gas conduit; flaps are installed in rotor guides. Engine is provided with heat-insulating coat on inner surface of rotor and on outer surface of stator in working stage, radiator fins joined with compression stage stator, castors one of which is mounted on end sides of flaps and other ones, on internal sides of guides. Compression stage has fan. EFFECT: improved design. 4 cl, 5 dwg
