FIELD: mechanical engineering; rotary engines. SUBSTANCE: engine has four toroidal chambers accommodating pistons rigidly coupled with working shaft. Each toroidal chamber is provided with two valves fitted in cylindrical slots. Valves, turning in slots, can overlap in turn the combustion chamber. It has also ring pistons of valve-actuating gear installed on their shafts and provided, each, with three sectors with sealing rings. EFFECT: improved performance of engine at high-mass-and-dimensional characteristics. 10 dwg
