Abstract

PURPOSE:To make it possible to control the discharge amount of a pump and to minimize the power loss by arranging plural rotors in parallel, furnishing a suction passage and an injection passage to each rotor, and providing a back flow check valve at the passage furnished to the rotor. CONSTITUTION:A main rotor 7 and an auxiliary rotor 8 are geared in parallel and rotatable freely. A main suction passage 3 and a main discharge passage 5 are arranged to the main rotor 7. An auxiliary suction passage 4 and an auxiliary discharge passage 6 are arranged to the auxiliary rotor 8. To a driving shaft 11, a spring 21 to press the driving shaft 11 against a pressure receiver 11a to receive the injection pressure is furnished. A back flow check valve 26 is furnished at the bend of the auxiliary discharge passage 6, and it closes the auxiliary discharge passage 6 by the decrease of the discharge pressure. In such a way, the discharge amount of the pump can be controlled, and the power loss is minimized.
