FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to interrupted combustion gas-turbine plants. According to invention, two rotors are installed in antiphase in housing with two working chambers. Surfaces of working chambers and rotors have form of rotating oval. Rotors are provided with several cavities of form in base like projection with surface of half of truncated cone partially enclosed by semiring arranged at a distance. Semirings, together with projections, form holes for ventilation with section in form of semiring, and channel is made over rotor generatrix to maintain pressure in spaces of cavities of rotor and working chamber when rotor is turned during "working stroke" phase. Rotors are furnished with system of seals consisting of double compression rings fitted on detachable locks installed on end faces of grooves and spring-loaded semirings fitted in slots made over mating lines of oval.
EFFECT: improved efficiency of engine in operation.
