を特徴とするベーンポンプ。 A plurality of vanes protruding outward in the radial direction are provided at equal intervals on the outer periphery of the rotor, and the tip of each vane is brought into contact with the inner peripheral surface of a cam ring provided on the outside of the rotor. A closed pump chamber is formed between each vane by abutting housing walls on both end surfaces, and fluid is sequentially sucked into each pump chamber from a suction port provided on the housing wall, and the fluid is drawn from each pump chamber into the housing wall. In a vane pump that sequentially compresses and discharges fluid to discharge ports provided in A vane pump characterized in that the chambers are communicated with a collective discharge chamber through channels of different lengths.
