FIELD: power engineering. ^ SUBSTANCE: proposed engine contains at least one hollow member installed for changing its geometric dimensions, movable member installed for movement at change of dimensions of hollow member, working medium supply system communicating with hollow member and outlet valve. Hollow member or its part is made in form of tubular structure engaging with movable member, being made if metal or its alloy. Outlet valve is pressure type, operating from pressure at change of dimensions of hollow member, being installed in housing, movable member, hollow member or working medium supply system. Outlet valve has pressure surface for closing at reduction of dimensions of hollow member or at reduction of pressure inside hollow member. At least one elastic element is provided operating constantly to open valve and at least one more elastic element to provide tight closing of valve. Valve is made as nondetachable part or as assembly of several parts. ^ EFFECT: increased efficiency and power output, reduced noises, vibrations, provision of low weight and low cost. ^ 5 cl, 1 dwg |
