Claims (1)
- 回転するロータと、このロータから摺動可能に突出する複数のベーンと、このベーンの先端部を摺接させて各ベーンの間にポンプ室を画成するカムリングと、前記ロータに対する前記カムリングの偏心量を変えてポンプ室の容積を可変とする可変容量機構と、この可変容量機構に導かれる作動流体圧力を制御して前記カムリングを移動する制御バルブと、前記ロータと前記ベーンと前記カムリングとを収容するポンプボディとを備える可変容量型ベーンポンプであって、
前記制御バルブを収容する制御バルブハウジング部が前記ポンプボディに一体形成され、この制御バルブハウジング部が前記ポンプボディにおいて前記ポンプ室の容積が収縮する吐出領域を囲む高圧側壁部に連接して形成され、
前記制御バルブハウジング部が前記吐出領域に対して前記ロータの回転中心軸方向についてオフセットされ、
前記ポンプボディに前記制御バルブハウジング部と前記高圧側壁部とに連接して隆起する補強リブが形成され、
前記補強リブの内側に第一流体圧通路、第二流体圧通路がそれぞれ形成され、この第一流体圧通路、第二流体圧通路によって導かれる作動流体圧によって前記カムリングを駆動する構成としたことを特徴とする可変容量型ベーンポンプ。
