FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building, particularly, to engines operated on compressed air and intended for replacement of motors driving various machines and mechanisms, as well as for replacement of ICE drives. Proposed engine comprises stator 8 with inner cylindrical surface, flanges arranged at its ends with at least one inlet communicated with compressor air source and at least one outlet, rotor 10 arranged eccentrically inside stator 8. Rotor 10 is composed of a cylinder with at least two axial bores 11 directed along its axis and extending over cylinder periphery. Every said axial bore 11 communicates with outer cylindrical surface of rotor 10 via lengthwise groove or at least one coupling hole intended for coupling with inlet and outlet of stator 8. Said axial bores 11 are blank on both sides.
EFFECT: higher torque and efficiency, compact design.
