INTERNAL COMBUSTION ENGINE Russian patent published in 2012 - IPC F02B55/02 F01C1/22 F01C17/04 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine consists of section with volume of inner cavity of stator restricted by cylindrical surface with inner profile in the form of epicycloid. Inside stator volume coaxially to stator axis and with possibility of rotation against it there is installed cylindrical bar of shaft. Rotor is installed inside stator cavity. Engine is additionally provided with cylindrical pins of stator with rolling bushings. Profile in the form of hypocycloid of rotor plate is designed with possibility of simultaneous rolling along all the profiles of bushings of stator pins. Shaft plate is coaxially and rigidly fixed on shaft with cylindrical pins of stator rigidly fixed on it parallel to stator axis. Cylindrical ring of rolling bushing is installed on each pin of shaft coaxially and with possibility of rotation against pin axis. Outer surface of each bushing of shaft pin in stator profile has continuous point contact with inner cylindrical surface of one through annular hole of rotor plate larger in diameter. Rotor plate is coaxially and rigidly fixed inside rotor. Centres of annular holes of rotor plate are located on circuit line with diameter value equal to value of circuit diameter on which line shaft pins axes are located. Additional pins of stator are rigidly fixed in parallel to stator axis on inner surface of one of stator surface directed towards shaft pins.

EFFECT: simplifying the design, improving efficiency and operating reliability of engine.
