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
