FIELD: machine building.
SUBSTANCE: invention relates to rotary engine. Engine (110) comprises housing (112) with inner disk rotor (120) on drive shaft (114). Rotor (120) has piston (116). Rotor (120) is provided with annular working chamber (118) with inlet opening (142) and outlet opening (132). Prior to opening (142) there is through valve (130) made so that piston (116) can pass and chamber (118) is closed after it passes. Hole (142) is connected to external combustion chamber (140) for introduction of working medium into chamber (118). Chamber (140) comprises rotary unloading valve (156) for controlling air inlet through inlet opening (146) and into chamber (140), as well as rotary feed valve (158) for closing or opening inlet (142) into chamber (118). Chamber (140) comprises compression rod (150) to increase compression ratio in chamber (140). Rod (150) is configured to be pushed into chamber (140) between valve (156) to control air inlet through opening (146) and into chamber (140) and valve (158) to close or open hole (142) into chamber (118).
EFFECT: invention is aimed at creation of efficient rotary engine with low production and operational costs.
