FIELD: engines and pumps.
SUBSTANCE: invention relates to rotary engine composed of the housing (110) with the first rotary chamber (120) and second rotary chamber (130). The first rotor (150) is located in the first rotary chamber (120) while second rotor (160) is located in the second rotary chamber (130). Surface (122) of said first rotary chamber (120) features varying distance from the opposite surface of the first rotor (150). Two valves, first (170) and second (180), are located at the first rotor (150). At rotation of the first rotor (150), said valves (170, 180) contact with the surface (122) of first rotary chamber (120) to run in opposite direction relative to the first rotor (150) to make two isolated working chamber (A, B) in the first rotary chamber (120).
EFFECT: better tightness, engine longer life and higher efficiency.
