OPPOSITE CYCLE ROTARY PISTON ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: proposed engine consists of housing, single-throw shaft and rotor freely rotating on journal of crank in space of quadratic chamber. According to invention, housing of engine is made in form of two members of quadratic closed partitions getting one into the other and two end face covers closing the partitions and reducing them. Space formed by smaller closed partitions serves as working chambers and space between partitions serves as water cooling jacket. Combustion of compressed air- fuel mixture is performed in bypass tubular combustion chamber in water cooling jacket and closing delivery and working stroke valves pockets. EFFECT: improved efficiency of operation of rotary piston engine. 6 dwg
