Abstract (en)
Rotary piston engine (33) has two rotators (2,2a), in which 9-12 double acting rotary pistons (1,1a) are supported by fulcrum pins (3). The rotators form a hollow-shaped cylinder space with the housing (22) and a second gas-tight working chamber (4) in the two rotators for the rotary piston. The rotor rotates with the engine shaft (14) to the right, the rotor rotates with the engine shaft (14a) to the left and in such a way forms a flow direction for the working medium. By the displacement of the engine shafts, the rotators form working and pressure chambers (10) and the expansion chamber (20) with the rotary pistons. The upper piston working surface forms a tangent to the rotators. Additionally the double acting rotary pistons are suspended by a stopper (7) and strengthen with a heat-proof material plate (5,6).
