Claims (6)
- ポンプケーシング内に装着されたロータの回転によって、吸入ポートから吐出ポートへ流体を移送するポンプにおいて、前記吐出ポートに連通する吐出流路の流れ方向と同一方向に導入路が形成され、且つ該導入路は、前記吐出流路よりも細く形成され、前記導入路の導入開口部は吐出流体の流れ方向に対して略正面に位置させると共に、前記導入路を介して前記吐出流路と連通するチャンバが前記吐出流路の流れ方向の延長線上に形成され、前記導入路付近に前記吐出流路の流れ方向と異なる方向の流路が連通形成されてなることを特徴とするオイルポンプ。
- ポンプケーシング内に装着されたロータの回転によって、吸入ポートから吐出ポートへ流体を移送するポンプにおいて、前記吐出ポートに連通する吐出流路と、該吐出流路に流れ方向と同一方向に形成されると共に前記吐出流路よりも細く形成され且つ流れ方向に対して略正面に位置するように形成された導入路と、該導入路に前記吐出流路の流れ方向の延長線上に連通するチャンバと、前記吐出流路と連通すると共に該吐出流路の端部箇所の流れ方向とは異なる方向の流路とからなり、該流路は前記導入路付近となるように前記吐出流路に連結されてなることを特徴とするオイルポンプ。
- 請求項1又は2において、前記導入路はテーパ状に形成されてなることを特徴とするオイルポンプ。
- 請求項1,2又は3のいずれか1項の記載において、前記チャンバは複数形成されると共に、直列状に連通されてなることを特徴とするオイルポンプ。
- 請求項4において、前記複数のチャンバは、相互に容積が異なることを特徴とするオイルポンプ。
- 請求項1,2,3,4又は5のいずれか1項の記載において、前記流路と前記吐出流路とは、略直角に連通してなることを特徴とするオイルポンプ。
