ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; internal combustion engines for vehicles. SUBSTANCE: proposed rotary engine has housing with intersecting cylindrical spaces accommodating rotors provided with projections and cavities. Rotors are installed in housing spaces on shaft coupled by synchronizing drive. Housing has also accumulating chamber connected by channels with compression chamber, and combustion chamber. The latter is made in body of power rotor and is provided with outlet channel opening on side surface of rotor. Gas distribution through outlet channel is provided by valve made in form of split ring coaxial with power rotor and secured on end face wall of housing and operating into round slot made in power rotor which intersects outlet channel of combustion chamber. Gas distribution through intake channel of combustion chamber is provided by valve arranged in cavity of power rotor coaxially with rotor and secured in end face wall of housing. Valve is made in form of tube closed from one end and provided with port on side surface, port being arranged in level with intake channel of combustion chamber. Inner space of tube communicates with accumulating chamber. EFFECT: increased liter capacity of engine, reduced consumption of fuel and toxicity of exhaust gases. 31 cl, 11 dwg
