The inventive rotary internal combustion engine comprises coaxially arranged large-diameter (2) and small-diameter (5) tubular elements, which are mounted on a shaft (4) in such a way that they are mutually rotatable, and annular spaces which are formed by said tubular elements together with annular discs (6, 7). Annular slots are made in the tubular element (2) in such a way that spring loaded reciprocatingly movable compression (8) and conversion (9) blades, between which combustion chambers (10) are located, can be arranged. Shaped projections (11) are arranged on the outer surface of the tubular element (5) in such a way that they contact the blades (8, 9) and divide the annular space into compression (12) and conversion (13) chambers which are respectively provided with inlet (14) and outlet (15) channels alternately positioned after each projection. Camshaft mechanisms (23) for the compression blades (8) and camshaft mechanisms (24) for the conversion blades (9) are mounted on the shaft (4). The shape of the respective cams together with the blade movement limiters (38, 39) enables the blades to be fixed in the specified position or to be released for reciprocating movement. For improving hermiticity, the blades are designed to be composite and are provided with spring-loaded vanes and vane pushers, for which radial grooves (27) are made in the annular discs (6, 7). The engine is provided with the working chambers (12, 13) having an optimized shape. The reciprocating motions of the blades are additionally carried out by the action of the compressed gases of the air-fuel mixture.
