Description
WO2005/052356A2において、ポンプピストンが配置されているケーシングと、ポンプケーシングにおいて端面側に配置されているフランジとから成る高圧燃料ポンプが既に公知になっている。さらにフランジ及びケーシングにはポンプ駆動軸が支承されている。ポンプ駆動軸は偏心体及び多角形の構成を介してポンプピストンに運動を与える。ポンプピストンの上側に設けられている圧力室は低圧回路の流入通路と接続されている一方で、高圧回路の高圧弁と接続されている。
Claims (7)
- 内燃機関を運転するための高圧燃料ポンプであって、低圧回路及び高圧回路に接続されていて、かつ、ポンプケーシング(1)とポンプフランジ(2)とから成っており、該ポンプフランジ(2)を介して前記高圧燃料ポンプは内燃機関に取外し可能に固定されており、ポンプカムシャフト(3)が、少なくとも1つのポンプピストンの運動により低圧回路からの燃料を圧縮して高圧回路に圧送する、内燃機関を運転するための高圧燃料ポンプにおいて、
ポンプフランジ(2)は内側の部分(4)と外側の部分(5)とに分割されており、内側の部分(4)はポンプカムシャフト(3)の支承部(6)を収容し、外側の部分(5)は低圧回路のエレメントを収容し、
内側の部分(4)と外側の部分(5)とは一致する固定点(13a,13b)を介してポンプケーシング(1)に取外し可能に固定されていることを特徴とする、内燃機関を運転するための高圧燃料ポンプ。 - ポンプフランジ(2)の外側の部分(5)は、ポンプケーシング(1)の燃料通路との接続のために環状溝(7,8)を有していることを特徴とする、請求項1記載の高圧燃料ポンプ。
- 内側の部分(4)は少なくとも1つのシャフトシールリング(9)を有していることを特徴とする、請求項1又は2記載の高圧燃料ポンプ。
- 流入通路(10)と、戻し通路(11)と、低圧回路の調量ユニット(12)とが外側の部分(5)に組み込まれていることを特徴とする、請求項1から3までのいずれか一項記載の高圧燃料ポンプ。
- 外側の部分(5)は内側の部分(4)を介して案内されることを特徴とする、請求項1から4までのいずれか一項記載の高圧燃料ポンプ。
- 外側の部分(5)は前記案内のために内側の部分(4)寄りの端面に突条片(14)を有していることを特徴とする、請求項5記載の高圧燃料ポンプ。
- 外側の部分(5)は前記内燃機関寄りの側にねじ固定点を有していることを特徴とする、請求項1から6までのいずれか一項記載の高圧燃料ポンプ。
