ROTARY INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2008 - IPC F02B55/14 F02B53/06 F01C19/10 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed rotary internal combustion engine has cylindrical body divided by cross partition into two sections with intake and discharge ports and two-section rotor with radial slots. Rotor is rigidly connected by common shaft and arranged in corresponding sections with surface contact in end face parts and linear contact in cylindrical parts of body. Member dividing working chamber between body and rotor, namely, gate, is installed in radial slot of each rotor for radial displacement to form variable-volume chambers for intake, compression, expansion and exhaust of gases. According to first design version, engine has two compression chambers arranged crosswise one over the other, with two side cutoff from corresponding variable-volume cambers by means of values adjusted for opening-closing. Camshaft is driven by power takeoff shaft through gear train. Engine is provided with two support shafts with rockers; spools in form of round rod with cutout to take in and discharge gases from each section, with toothed sectors, levers and springs; three-layer extensible gates with labyrinth seal; U-shaped seals in body in zone of constant of rotor with body over cylindrical generatrix and extension along end face surfaces from both sides to rotor shaft. All working processes take place in each section at two revolutions of shaft. According to second design version, engine has two parallel compression chambers arranged in thicker part of body, with two side cutoff from corresponding variable-volume chambers by means of valves adjusted for opening-closing. Camshaft is driven by power takeoff shaft through gear train. Engine is provided with two support shafts with rockers; three-layer extensible gates with labyrinth seal; U-shaped seals in body in zone of constant linear contact of rotor with body over cylindrical generatrix and extension along end face surfaces at both sides to rotor shaft.

EFFECT: improved reliability and increased efficiency of engine.
