    Abstract: A rotary valve of an internal combustion engine intake and exhaust system includes an inner rotor (1), an outer rotor (2) jacketed on the inner rotor and a valve body (3) set outside of the outer rotor, wherein the inner rotor (1) is hollow, and one end is closed, the other is an open-end, the sides of the inner rotor (1), the outer rotor (2) and the valve body (3) have at least one set of side openings correspondingly, when the inner rotor and the outer rotor rotate inversely, the same set of the side openings are turned on discontinuously, the inner rotor and the outer rotor are connected with a drive unit controlled by timing gear separately. The rotary valve is placed in the intake path or exhaust path of the internal combustion engine to minimize the vibration and the voice, and the engine can change phase conveniently.
