ROTOR-TYPE INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: manufacture of engines. SUBSTANCE: engine consists of two sections. Each section has one of two cylindrical parts of rotor interconnected by common axle and has working chamber around rotor which is divided into two chambers of varying volume by zone of conjugation of circle of rotor and housing and by piston extending from rotor body and engageable with walls of working chamber. Varying-volume chambers of first section are used for suction and compression of combustible mixture and chambers of second section are used for working stroke including forcing out the waste gases. At the end of compression chamber there is inlet of bypass hole made in partition between sections inclining in zone of conjugation with lateral wall of second cylindrical part of rotor which is provided with bow-shaped groove brought in communication with working stroke chamber which may be matched with outlet of bypass hole during bypass of compressed mixture. End of first working chamber and beginning of second working chamber are matched in one line. Piston of second section is in angle advance relative to that of first section which defines final volume of compressed mixture by the moment of ignition. Under-piston chamber of first section is brought in communication with compression chamber by groove provided in piston and under-piston chamber of second section is brought in communication with working stroke chamber. Part of area of lower face of pistons is taken by spring-loaded rod connected to it and engageable with its hole in rotor. EFFECT: enhanced reliability. 7 dwg
