Claims (5)
- 少なくとも油圧ポンプと作動油タンクとを一体化し、前記油圧ポンプのハウジングが前記作動油タンク内に収容される構成の油圧ポンプユニットで用いられる油圧ポンプであって、
前記ハウジングが油圧ポンプの回転軸に垂直な面で分割された本体側ハウジングと蓋側ハウジングとを備え、この蓋側ハウジングを本体側ハウジングに対して、ポンプ許容油圧に対応した所定圧力で油密に当接させ、前記所定圧力を越える作動油を、前記本体側ハウジングと蓋側ハウジングとの間から前記作動油タンクに漏れ出させることを特徴とする油圧ポンプ。 - 前記所定圧力での油密な当接は、前記蓋側ハウジングの取付孔と締付ボルトとの間に嵌め込まれ、前記本体側ハウジングに対して該締付ボルトの締付固定を達成させるスペーサと、締付固定後の該締付ボルトの首下と前記蓋側ハウジングとの間に介在して前記所定圧力を発生するスプリングとによって実現されることを特徴とする請求項1記載の油圧ポンプ。
- 前記所定圧力での油密な当接は、前記本体側ハウジングに締付ボルトで固定され、全体が弾性体で構成され、その一部分が前記ポンプ許容油圧を受けた場合に弾性変形するように構成された蓋側ハウジングによって実現されることを特徴とする請求項1記載の油圧ポンプ。
- 請求項1から3のいずれか記載の油圧ポンプを備えたことを特徴とする油圧ポンプユニット。
- 請求項4記載の油圧ポンプユニットに、更に、少なくとも、前記油圧ポンプを駆動する電動モータ、前記油圧ポンプからの作動油によって駆動される油圧アクチュエータを一体化したことを特徴とする油圧駆動ユニット。
