Description
また、第2背圧溝は、第2ポンプ部の全域および第1ポンプ部のオイル吸入部位を含めて、背圧オイルとして比較的低圧の第2吐出オイルを供給するように設けられているため、第2ポンプ部の全域でベーンの押付力が低下し、ベーンと内周カム面との間の摺動抵抗に起因するトルク損失が低減される。
Claims (1)
- 内周カム面を有するハウジングと、
外周面が前記内周カム面に対向するように前記ハウジング内に回転可能に配設されたロータと、
該ロータの外周面に開口するように設けられた複数のスリット内にそれぞれ嵌め入れられることにより、先端部が該スリットから突き出すように該ロータの径方向に進退可能に放射状に配設された複数のベーンと、
該複数のベーンの前記先端部を前記内周カム面に押し付けるための背圧オイルを前記スリットの底部に供給できるように、前記ハウジングに設けられた背圧溝と、
を有し、且つ、前記内周カム面は、前記ロータの回転に伴ってオイルを吸入して吐出する一対の第1ポンプ部および第2ポンプ部が該ロータの回転方向に区分して設けられるように、該ロータの回転軸線からの径寸法が増減設定されているとともに、
前記第1ポンプ部の第1吐出圧に比較して前記第2ポンプ部の第2吐出圧が低圧に調圧されるように用いられるベーン式オイルポンプにおいて、
前記背圧溝は、前記第1吐出圧の第1吐出オイルが導入される第1背圧溝と、前記第2吐出圧の第2吐出オイルが導入される第2背圧溝とを独立に備えており、
前記第1背圧溝は、前記第1ポンプ部のオイル吐出部位において、前記背圧オイルとして前記第1吐出オイルを前記スリットの底部に供給するように設けられ、
前記第2背圧溝は、前記第2ポンプ部の全域および前記第1ポンプ部のオイル吸入部位を含めて、前記背圧オイルとして前記第2吐出オイルを前記スリットの底部に供給するように、前記回転軸線まわりにおいて前記第2ポンプ部から前記第1ポンプ部のオイル吸入部位まで延長して設けられている
ことを特徴とするベーン式オイルポンプ。
