Claims (4)
- 燃料噴射システムにおける燃料高圧発生のためのラジアルピストンポンプであって、
−ポンプハウジング(1)が設けられており、
−ポンプシャフトが設けられており、
−該ポンプシャフトに対して半径方向に配置された少なくとも1つのシリンダインサート(2)が設けられており、該シリンダインサート(2)内にシリンダ室(3)が形成されており、該シリンダ室(3)内でピストン(4)が往復運動可能に案内されており、
−シリンダインサート(2)の端面(5)が、ポンプハウジング(1)に設けられた平らに加工された平坦部(6)に接触していて、該平坦部(6)と緊締手段によって緊締されており、
−シリンダインサート(2)が少なくとも1つの吸込通路(8)を有しており、該吸込通路(8)によって燃料がシリンダ室(3)に供給され得るようになっており、
−シリンダインサート(2)が少なくとも1つの高圧通路(9)を有しており、該高圧通路(9)を介して燃料がシリンダ室(3)から流出し得るようになっており、
−吸込通路(8)と高圧通路(9)とが、それぞれシリンダインサート(2)の端面(5)に開口しており、
−ポンプハウジング(1)に第1の対応する通路(10)と第2の対応する通路(11)とが配置されており、両通路(10,11)がポンプハウジング(1)の平坦部(6)に開口していて、吸込通路(8)もしくは高圧通路(9)とほぼ整合している、
形式のものにおいて、
シリンダインサート(2)の端面(5)および/またはポンプハウジング(1)の平坦部(6)が、意図的に加工成形された隆起したシール範囲(12,13,14)を有しており、該シール範囲が、シリンダインサート(2)の端面(5)全体ならびにポンプハウジング(1)の平坦部(6)全体に比べて小さく形成されていて、当該シール範囲(12,13,14)で高い面圧が得られるようになっており、
吸込通路(8)を取り囲むように第1の隆起したシール範囲(12)が形成されており、高圧通路(9)を取り囲むように第2の隆起したシール範囲(13)が形成されており、
第1および第2の隆起したシール範囲(12,13)を取り囲むように、付加的な第3の隆起したシール範囲(14)が形成されており、該第3の隆起したシール範囲(14)が第1および第2の両隆起したシール範囲(12,13)を完全に取り囲んでおり、
ポンプハウジング(1)の平坦部(6)に、第3の隆起したシール範囲(14)により取り囲まれた面の内側で、第1の隆起したシール範囲および/または第2の隆起したシール範囲からの、場合によっては生じる漏れ流を排出しかつシールシステムを監視するための排出通路(16)が形成されている
ことを特徴とする、燃料噴射システムにおける燃料高圧発生のためのラジアルピストンポンプ。 - 第1および第2の隆起したシール範囲(12,13)が、吸込通路(8)もしくは高圧通路(9)の中心をほぼ環状に取り囲むように形成されている、請求項1記載のラジアルピストンポンプ。
- 高圧通路(9)を取り囲むように付加的なエラストマパッキンが配置されている、請求項1または2記載のラジアルピストンポンプ。
- 前記エラストマパッキンがリングパッキンとして形成されていて、該リングパッキンの外周面が支持リング(18)によって支持されている、請求項3記載のラジアルピストンポンプ。
