ROTARY PISTON ICE Russian patent published in 2013 - IPC F02B55/02 F01C1/356 

FIELD: engines and pumps.

SUBSTANCE: rotary piston ICE comprises housing, rotor, shaft, air-fuel mix preparation system, ignition system and exhaust gas withdrawal system. Rotor is arranged inside said housing and coupled by compression rings therewith. One rotor is rigidly fitted at the shaft. Rotor is shaped to torus with surface skewed over elliptical line parallel with the shaft. Compression rings are fitted in round-section points most remote from torus axis. Housing represents split hollow torus, its part being screwed together by threaded elements made at torus outer side. Spring-loaded choke compression-coupled with housing and rotor is arranged between intake and discharge ports. Choke end rests on rotor. Two radial spring-loaded and cam-adjustable chokes resting on rotor and compression-coupled with housing and rotor are arranged at opposite side of the housing. Said chokes are made up of two conformable plates moving radially relative to each other.

EFFECT: higher efficiency, reduced vibration.
