FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises stator 1 with three-vertex working chamber. Camshaft 2 is arranged coaxially inside working chamber 2. Engine comprises power mechanism with timing gearing and elliptical rotor-piston 3. The latter is pin-jointed at camshaft 2 to get in contact with seals 8 over elliptical surface to make three sealed variable-volume chambers communicated with gas transfer system. Stator 1 incorporates additionally, at least, one more working chamber separated from the first one by disc 24 with bore for shaft passage and system of channels communicated with gas transfer system. Every seal 8 is furnished with a sealed system of channels filled with sodium. Portion of sealed element surface arranged inside working chamber is plated with refractory material.
EFFECT: higher output, longer life.
