ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2021 - IPC F02B53/06 F02B53/08 F01C1/46 

FIELD: engine construction.

SUBSTANCE: invention relates to engine construction. The engine contains a compressor rotor and a turbine rotor. In a single groove of the working rings of the compressor and the turbine, two identical combustion chambers are installed sequentially along the rotation of the engine shaft to form a single housing. Between the inlet channel of each combustion chamber in the working ring of the compressor and each inlet channel of the single housing of the combustion chambers, there is an inlet valve of the spool type in the form of a plate with two windows, which has the possibility of reciprocating movement by means of an electromagnetic device of the compressor. Between each outlet channel of the single housing of the combustion chambers and the outlet channel of each combustion chamber in the working ring of the turbine, there is a spool-type outlet valve in the form of a plate with two windows, which has the possibility of reciprocating movement by means of an electromagnetic device of the turbine. A split spacer sealing ring with an annular groove is installed between the side surface of the compressor rotor and the side cheek of the compressor, which is tightly pressed by the outer surface to the inner surface of the compressor working ring in a fixed position when the cut is located after the radial working valve of the compressor during the rotation of the engine shaft.

EFFECT: technical and economic performance of the engine is increased due to the presence of two combustion chambers and the introduction of sealing elements both in the compressor and in the turbine, which makes it possible to avoid idle movements of the turbine rotor, improve the tightness of the working cavities, which increases the specific power of the engine and reduces fuel consumption.
