- 駆動軸に連結されたロータと、
前記ロータに対して径方向に往復動自在に設けられる複数のベーンと、
前記ロータの回転に伴って前記ベーンの先端が摺動する内周面を有するカムリングと、
前記ロータと前記カムリングと一対の隣り合う前記ベーンとによって区画されるポンプ室と、
前記ポンプ室に作動流体を導く吸込ポートと、
前記ポンプ室から吐出される作動流体を導く吐出ポートと、
前記吸込ポートの開口縁部から前記ロータの回転方向とは逆方向に向かって形成されるノッチと、を備え、
前記ポンプ室の容積が収縮する吐出領域から前記ポンプ室の容積が拡大する吸込領域へと前記ロータの回転に伴い遷移する領域である遷移領域では、前記ポンプ室は、前記吐出ポートに連通し、かつ、前記ノッチを通じてのみ前記吸込ポートに連通していることを特徴とするベーンポンプ。 - 前記ロータの中心に対する隣り合う前記ベーン間の角度間隔は、前記吸込ポートと前記吐出ポートとの間の角度間隔以下に設定されると共に、前記ノッチと前記吐出ポートとの間の角度間隔は、隣り合う前記ベーンの角度間隔より小さく設定されることを特徴とする請求項1に記載のベーンポンプ。
