INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B53/14 F02B55/02 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine comprises piston disk (16), along periphery of which in piston grooves (17) pistons (1) are hingedly installed in supports. Pistons are arranged with the possibility of displacement transformed with the help of at least one disk (16) into rotary motion of output shaft. Working cavities are fixed around piston disk (16). Working cavities are equipped with sparking plugs (7) and valves for injection of combustible mixture and have openings (10) for exhaust of spent gases. Piston disk (16) is fixed to additionally installed toothed disk. Toothed disk is arranged with teeth on one side, at that teeth are installed in concentric rows, and is rigidly fixed to piston disk (16) on the other side. Pistons (1) are radially spring-loaded with springs and equipped each with rolling element. Rolling element is installed in piston disk (16) groove perforated by windows. Working cavities are separated each from window of groove by shutter. Shutter has curvature equal to groove curvature, rests on spring-loaded guide and is installed with the possibility of piston (1) turn under action of rolling element and insertion of the latter into working cavity with creation of combustion chamber. On the other side of toothed disk output shaft gear is installed with the possibility of interaction with teeth of the latter, which is installed with the possibility of displacement.

EFFECT: expansion of control range, improved layout resources on vehicle, increased efficiency factor.
