に嵌挿されているベーンポンプ。 The rotor is rotatably driven in a space within the inner cam surface in the pump housing, and the rotor has a plurality of slits formed in the radial direction, and the bottom of each slit has a passage on the discharge port side. A back pressure chamber in the axial direction is formed in communication via a check valve that prevents the flow of working fluid from the slit to the discharge port side, and a vane is fitted into each slit so as to be slidable in the radial direction. .
