PURPOSE:To protect the engine from an abnormal wear, by simply constructing an inner circumferential pattern of the cylinder and outer circumferential pattern of the rotor both into a cylindrical shape, facilitating an easy manufacturing process, and arranging an end of the rotary separating member in such a manner as to make a contact with inner circumferential surfaces of the casing. CONSTITUTION:On the top portion of an engine main unit 1, are provided a fuel actuating unit 10 and an output operating unit 50 of almost the same construction in a two-staged manner on the same shaft core. Casings 11, 51 having cylindrical inner circumferential surfaces are provided in each of the above units 10, 50. An output shaft 19 is further provided concentrically to the casings as a common rotary shaft. To said output shaft 19 are secured rotary separating members 12, 52 having separator plates 13, 53 whose outer edge sides make a contact with the inner circumferential surfaces of the casing. A turning ring 22 having a link shaft 21 is fitted to a mandrel 20 eccentrically provided in the bottom of the casing, and rotors 17, 54 are engaged to the output shaft 19 in such a manner as to be coupled through the link shaft 21. In the casing, is also provided an air-tightly keeping unit 30 including a contact element with a rocking motion capable. |
