Abstract
Description
従来のバキュームポンプにおいては、ハウジングのポンプ室で回転するロータの摺動部分に潤滑油を供給するように構成されており、摺動部分を潤滑した後の潤滑油はロータの回転に伴って、気体とともに排出通路からポンプ室の外部へ排出されるようになっている。
ベーンポンプ1は図示しないエンジンルームの側面に固定されており、例えば、図示しないブレーキ倍力装置の負圧源として機能するようになっている。
ベーンポンプ1は、略円形のポンプ室2Aを有する段付円筒状のハウジング2と、ポンプ室2A内に配置されるとともにポンプ室2Aの中心に対して軸心を偏心させて配置されたロータ3と、ポンプ室2A内に配置されるとともにロータ3とともに矢印方向に回転されてポンプ室2A内を常時複数の作動空間に区画するベーン4と、ハウジング2における大径部2Bの開口、すなわちポンプ室2Aの一端開口を閉鎖するカバー5とを備えている。

Claims (2)
- 内部にポンプ室を有するハウジングと、前記ポンプ室内に配置されるとともにロータによって回転されて前記ポンプ室を複数の作動空間に区画するベーンと、前記ポンプ室の内周面と摺動する摺動面が形成されて前記ベーンの先端に取付けられるキャップと、を有するバキュームポンプにおいて、
前記キャップの摺動面は前記ロータの回転軸方向視で円弧形状に形成され、
前記キャップにおける摺動方向の幅は、前記キャップの摺動面の円弧形状を含む円周のうち前記ポンプ室の内周面と接するべき仮想領域である摺動角領域における摺動方向の幅よりも小さく、かつ、前記摺動角領域のうち前記摺動面に加わる荷重が所定の値よりも大きくなる高荷重領域における摺動方向の幅よりも大きく形成される、
ことを特徴とする、バキュームポンプ。 - 前記ベーンの幅は前記キャップにおける摺動方向の幅と等しくなるように形成される、
ことを特徴とする、請求項1に記載のバキュームポンプ。
