とを特徴とするベーンポンプ。A rotor that is rotationally driven by a rotating shaft, a large number of vanes that are attached to the rotor so as to be able to protrude and retract in substantially radial directions, and a work that accommodates each of these vanes and the rotor inside and forms spaces between adjacent vanes. A cylindrical cam ring having a chamber formed axially symmetrically on the outer peripheral side of the rotor, and a casing that houses the cam ring and forms an annular suction chamber with the outer peripheral surface of the cam ring to guide working fluid from the suction passage. , the working fluid sent into the suction chamber from the suction passage is sucked into each of the working chambers through upstream and downstream suction ports provided on the upstream and downstream sides of the suction chamber, In a vane pump that pressurizes and discharges to the outside by a change in volume of a working chamber due to rotation of a rotor, the cross-sectional area of the suction chamber from the suction passage to the upstream suction port is defined as A vane pump characterized in that the cross-sectional area from the upstream suction port to the downstream suction port is larger by an amount corresponding to the amount of working fluid sucked into the pump chamber from the upstream suction port.
