Claims (1)
タの外周に前記カムリングの内周カム面に摺接す
る複数のベーンを保持し、この複数のベーンの背
部に設けた背圧室に吐出後の圧油を導入するよう
にしたベーンポンプにおいて、前記カムリングの
前記ベーンと接触するカム面に深さが２〜１０μ
mmでかつ占有面積率が１０％〜８０％のランダム
なスジを設けたことを特徴とするベーンポンプ。 A plurality of vanes that are in sliding contact with the inner circumferential cam surface of the cam ring are held on the outer periphery of a rotor that is rotatably arranged inside the cam ring, and the pressurized oil after being discharged is discharged into a back pressure chamber provided at the back of the plurality of vanes. In the vane pump, the cam surface of the cam ring that contacts the vane has a depth of 2 to 10 μm.
A vane pump characterized by providing random stripes with a diameter of mm and an occupied area ratio of 10% to 80%.
