INTERNAL COMBUSTION ENGINE BY POTAPOV Russian patent published in 2012 - IPC F02G1/43 F01C1/348 F01C1/356 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine comprises a volumetrical rotor-piston machine, a reservoir-heater and a reservoir-cooler. Chambers of the rotor-piston machine external to the rotor-piston are formed by two flat end covers, the inner cylindrical cavity of the stator, the external surface of the rotor-piston and the flat external partition-gate. The rotor-piston machine is equipped with a fixed cylindrical core arranged coaxially to the stator cavity. The rotor-piston is made in the form of a pipe adjacent with its outer surface to the inner surface of the cylindrical cavity of the stator, and with the inner surface adjoining the outer cylindrical surface of the core. In the inner cavity of the rotor-piston there is a flat inner partition-gate arranged in parallel to the stator axis, forming inner chambers. At both sides from the inner partition-gate in the core there are windows of inner chambers. Via the reservoir-cooler one window of the inner chamber and one window of the outer chamber are connected, namely, windows arranged at the minimum distance from each other, when measuring the centre of cross sections of these windows in the area of their crossing with appropriate chambers. The other window of the inner chamber and the other window of the outer chamber are connected via the reservoir-heater. Between the window of the inner chamber and the reservoir-heater there is a check valve.

EFFECT: invention achieves more complete usage of the inner volume of the stator.
