ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F01C19/08 F02B55/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the engine building. Essence of invention consists in the fact, that engine comprises body with the working ring having inner and outer cylindrical surfaces. In the working cavities made in the form of the disc with projection compressor rotor and made in the form of cup with rigidly fixed to the shaft bottom turbine rotor are installed. Compressor rotor is installed with possibility of displacement along the motor shaft by means of resilient members, embedded in the outer side flange and adjacent to the introduced additional external side flange, made in the form of disk, by the outer diametrical surface tightly entering inside the working ring with possibility of moving therein parallel to the motor shaft axis, and connected to the outer side flange. Compressor rotor is provided with beads located on its lateral surfaces along the outer diameter and adjacent to the inner side flange on one side and to the additional external lateral flange on the other side. On the turbine rotor bulge inner diametrical surface spring-loaded sealing rings are installed with possibility of movement parallel to the motor shaft axis, in which the outer end surfaces are tightly fitted to the outer and inner side flanges, and the inner end surfaces are made in the form of protrusions and recesses. One ring each protrusion enters into the other ring cavity with the single ring formation with possibility of its expansion parallel to the motor shaft.

EFFECT: increase in the engine operation efficiency by improvement of the working volumes sealing.
