Description
Claims (10)
- パワーステアリング装置のための外歯車ポンプであって、該外歯車ポンプが、ハウジング(12)を有し該ハウジング(12)の端面がフランジ(26)及びカバー(30)によりそれぞれ閉じられている液圧外歯車ポンプ(10)を備えたものにおいて、
上記外歯車ポンプ(10)が、上記フランジ(26)及び上記カバー(30)が少なくとも1つの保持部品(40,56)により互いに締付けられた、組立てられた構造ユニットであり、
上記外歯車ポンプ(10)は、他のハウジング区分(46)内に形成された共振空間(48)に挿入されており、
上記共振空間(48)は上記外歯車ポンプ(10)の高圧側接続部(32)と接続し、これにより該外歯車ポンプ(10)が作動するとき該ポンプに対する外部からの作用が存在する、即ち、該外歯車ポンプ10を取り巻く液圧流体内に結果として生じる圧力が、カバー30、ハウジング12及びフランジ26のためのシールの押圧力を支援する、
ことを特徴とする、外歯車ポンプ。 - 上記カバー(30)から上記フランジ(26)へ延びるネジ(56)の形をした数個の上記保持部品が設けられることを特徴とする請求項1に記載の外歯車ポンプ。
- 上記保持部品がブラケット形状のバネ素子(40)であることを特徴とする請求項1に記載の外歯車ポンプ。
- 上記バネ素子(40)が上記カバー(30)又は上記フランジ(26)のくぼみ(42)内に保持された中央の区分(40a)と、当該フランジ(26)又は当該カバー(30)の背後で係合する2つの区分(40c)とを有することを特徴とする請求項3に記載の外歯車ポンプ。
- 上記バネ素子(40)が波形の区分(40a)を有することを特徴とする請求項3又は4に記載の外歯車ポンプ。
- 上記波形の区分(40a)が上記中央の区分(40a)であることを特徴とする請求項4及び5に記載の外歯車ポンプ。
- 上記ハウジング(12)に関して上記フランジ(26)及び上記カバー(30)を位置決めするためのセンタリングピン(36、38)を設けたことを特徴とする請求項1ないし6のいずれかに記載の外歯車ポンプ。
- 上記フランジ(26)に、同フランジ(26)に接して位置する素子に関して上記ポンプ(10)を位置決めするためのセンタリングピン(36)を設けたことを特徴とする請求項1ないし7のいずれかに記載の外歯車ポンプ。
- 上記センタリングピン(36)は上記ハウジング(12)に関して上記フランジ(26)を位置決めするためにも設けられていることを特徴とする請求項8に記載の外歯車ポンプ。
- 2つの噛み合う歯車(14、16)を備えた歯車セットが上記ハウジング(12)内に収容され、上記歯車がシャフト(18、20)上に各々配置されるか又はシャフト(18、20)と一緒に一体部品として構成され、上記シャフト(18、20)が2つの対向する軸受台(22、24)に装着され、一方の上記シャフトが当該ハウジング(12)の上記端面から延び出ることを特徴とする請求項1ないし9のいずれかに記載の外歯車ポンプ。
