A rotary piston type working machine comprises a cylinder body (1) and a transmission shaft (21). A circle of ring-shaped groove is formed in the cylinder body (1). A first sealing piece (22) is connected to the transmission shaft (21) and seals the ring-shaped groove. The first sealing piece (22) and the cylinder body define a closed ring-shaped cylinder. The ring-shaped cylinder is internally provided with at least one piston (23). The cylinder body (1) is provided with at least one stopping-block installation opening (15). The stopping-block installation opening (15) is internally provided with a second sealing piece (16) supported by a rotary shaft. The second sealing piece (16) is provided with at least one piston through hole. When the piston (23) rotates to the second sealing piece (16), the second sealing piece (16) rotates to the position where the piston through hole corresponds to the piston (23), so that the piston (23) passes through the piston through hole, and the second sealing piece (16) seals the stopping-block installation opening (15) and chambers at the two sides in the movement process. By means of the present invention, the energy loss and the friction of the working machine are reduced, the service life is prolonged, the compression ratio is large, the working efficiency is high, the combustion is sufficient, the pollution discharge is small and the energy-saving and environment-friendly effects are achieved. |
