INTERNAL COMBUSTION ENGINE Russian patent published in 2015 - IPC F02B55/02 F01C1/22 F01C17/06 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine comprises at least one rotor section, its mechanism contains power pin coupling, and is installed inside the rotor. The rotor has radial external profile in form of hypocycloid. At that the power shaft of the section comprises two coaxial and mutually opposite shafts, connected inside the rotor with each other by three pins of the power pin coupling. The pins parallel to the shaft axis are secured on the opposite shaft disks. The shaft disk profile has shape with rounded tips, number of tips repeat the shape of the external rotor profile. On each pin a round roller with counterbalance is installed by its eccentric hole with possibility of rotation and sliding. By its external cylindrical surface each roller is installed with possibility of rotation and sliding over the internal cylindrical surface of one of through round holes of the middle power disk of the rotor, being the counterpart of the power pin coupling for the pin disks of the shaft.

EFFECT: higher efficiency and reliability of the engine operation.
