Abstract

PURPOSE:To remarkably decrease pulsation of suction and delivery power of a pump, by concentrically forming an internal peripheral surface of a housing with a rotor and arranging the displacement of the pump to a constant rate of change. CONSTITUTION:The displacement of a pump, contacted with across both ends of the first and second suction ports 32, 33, is always constant in no relation to revolution of a rotor 16, and the displacement of the pump, communicated to the first and second suction ports 32, 33, increases by a portion C increased with rotation of the rotor 16. Since the internal peripheral wall 13'a of a housing is concentrically formed with the rotor 16 in a portion between suction and delivery ports, the displacement is increased at constant proportion to rotary motion of the rotor 16, and a constant change rate of the displacement can remarkably decrease pulsation of suction and delivery power.
