Abstract

PURPOSE:To contrive to lowering of noise by opening a discharge port, being interconnected to an exhaust port, leading in a high pressure fluid and discharging this high pressure fluid in the rotational direction of a rotor, to an operating chamber formed with the rotor and an inner wall of a rotor housing. CONSTITUTION:Each of operating chambers 6, 7 is formed in a portion surrounded by two top faces 2a, 3a of rotors 2, 3 and an inner wall 1c of a rotor housing 1. Discharge ports 1a, 1e to be interconnected to an exhaust port 1b via conductors 8a, 8b are formed at both sides of the rotor housing 1. With this constitution, pressure of the high pressure fluid to be spouted to the operating chamber is in no case checked to rotation of the rotor, so that it is effectively absorbed as rotational energy.
