||PCT/FR2013/000192||BEGUIN Jean Luc||BEGUIN Jean Luc|
Rotary internal combustion engine with a variable compression ratio. The invention relates to the production of a heat engine which has a simple design and a high yield and is less pollutant than current motors. This is based on the use of a sub-toroid provided with a blade (PI) at one of the sections thereof inside which a piston (PV) gravitates, formed from blades (PV1) and (PV2) plus a hub, with variable geometry, about the same axis (x'-x) as the rotational axis of the toroid. A gear formed from four eccentric wheels allows the blades to alternately move closer or move away to define the combustion chambers, turn by turn, large or small, in order to generate the rising of a gas detonating the cycle of admission, compression, explosion and exhaust. A standard cylinder head welded to the toroid allows the inflow-outflow management of the gaseous flow, by means of the valves (SI) to (S4). The engine is to replace current engines.
