PURPOSE:To reduce rotation vibration and obtain a flat output torque efficiency from a low speed to a high speed by pivotally supporting circular inner rotors of a smaller diameter than circular operation chambers in them making them contact at one point respectively, and forming an exhaust port before the inner contact point and a suction part on the back of the inner contact point. CONSTITUTION:Two circular operation chambers 2, 3 are formed in parallel to each other and partly connected with each other in an outer housing 1, and circular inner rotors 5, 6 of a smaller diameter than the inner diameter of the operation chambers 2, 3 are contained in the chambers respectively to rotate eccentrically freely. The side of the first operation chamber 2 is composed as a rotary engine part, and the side of the second operation chamber 3 is as a supercharger part. An exhaust port 11 is formed in the first operation chamber 2,and an auxiliary exhaust port 12 is formed adjacent to it before an inner contact point 13 of the inner rotor 5. A suction port 15 is formed in the second operation chamber 3, and an auxiliary suction port 16 is formed adjacent to it on the back of an inner contact point 14 of the inner rotor 6, while a fuel injection port 17 is formed between the suction port 15 and a connecting part 7. |
