FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises rotor, vanes, at least, two housings, seals and two sections: hot and cold. Rotors of said sections are rigidly fitted on common shaft. Hot section rotor is longer than that in cold section. Cold section vane operating area and chamber volume are larger than those in hot sections. Engine comprises cold section inlet, cold section outlet, got section inlet and hot section outlet. Hot and cold section chambers are communicated via two tubes, one extending through cooling chamber and another one extending through heating chamber. Both said tubes cross regeneration chamber. Valve is arranged on line extending from regeneration chamber to cold section. Vane parts are located on opposite sides of rotational axis. Every vane is completely extended and fixed relative to rotating rotor, at the moment when distance between opposite walls equals vane length.

EFFECT: higher efficiency.
