Claims (1)
レートに圧力導入溝を形成し、吐出ポートからの
作動流体を前記圧力導入溝を介して背圧室に導く
ことによつてベーンをカムリングに押しつけるよ
うにしたベーンポンプにおいて、前記ロータの側
面に各背圧室からベーンの回転方向に向けて圧力
導入溝側へ傾斜した傾斜溝を形成したことを特徴
とするベーンポンプ。 A slit and a back pressure chamber are formed in the rotor, a pressure introduction groove is formed in the side plate, and the working fluid from the discharge port is guided to the back pressure chamber through the pressure introduction groove, thereby pressing the vane against the cam ring. 2. A vane pump characterized in that an inclined groove is formed on a side surface of the rotor, the groove being inclined from each back pressure chamber toward the pressure introduction groove side in the direction of rotation of the vane.
