Claims (1)
部に設けたベーン溝に円柱形のローラベーンを摺動自由
に組込み、ロータ回転により隣り合つローラベーンの間
に形成される油室の容積変化に応じて燃料を吸入、吐出
するベーンポンプにおいて、前記ローラベーンの円周面
と両底面が交わる端部を曲率を有する面に形成したこと
を特徴とする燃料ポンプ。Equipped with a rotor that rotates inside a cam ring, cylindrical roller vanes are freely slidably incorporated into vane grooves provided on the circumference of the rotor, and as the rotor rotates, the volume of the oil chamber formed between adjacent roller vanes changes. 1. A vane pump that sucks in and discharges fuel accordingly, characterized in that an end where a circumferential surface of the roller vane intersects with both bottom surfaces is formed into a surface having curvature.
