Description
本発明は、請求項1の上位概念部記載の燃料を噴射するための装置から出発する。
請求項1の特徴を有する本発明による燃料を噴射するための装置は、少なくとも1つの燃料噴射弁において電磁式の圧力増幅器が配置されていることによって、燃料噴射弁における圧力増幅が簡略化されて廉価に行われるという利点を有している。
本発明の実施例を図面に簡略化して示し、以下に詳しく説明する。
図1には電磁式の圧力増幅器を備えた燃料噴射弁が示してある。
Claims (8)
- 少なくとも1つの燃料噴射弁(1)を備えた燃料を噴射するための装置において、少なくとも1つの燃料噴射弁(1)に、少なくとも1つの電磁式の圧力増幅器(5)が配置されており、該少なくとも1つの電磁式の圧力増幅器(5)は少なくとも1つの燃料噴射弁(1)に直接前置されている形式のものにおいて、
電磁式の圧力増幅器(5)は独立した構成群であり、燃料噴射弁(1)の入口通路(8)に差し嵌められているか、またはクリップ留めされているか、または溶接されているか、またはプレス嵌めされており、燃料噴射弁(1)の入口通路(8)と、該入口通路(8)側の圧力増幅器(5)の端部の内壁との間において、リング状の部材が前記入口通路(8)と前記内壁とに接触するように設けられていることを特徴とする、燃料を噴射するための装置。 - 電磁式の圧力増幅器(5)が、燃料管路(2)と流れ接続されている、請求項1記載の装置。
- 燃料噴射弁(1)が、電磁式、またはピエゾ式、または磁歪式の燃料噴射弁である、請求項1記載の装置。
- 電磁式の圧力増幅器(5)が、励磁コイル(10)と、プランジャ(11)とを備えた電磁石(7)を有しており、プランジャ(11)が、電磁式の圧力増幅器(5)の圧力室(14)において軸線方向に可動に支承されたピストン(15)と作用結合されている、請求項1記載の装置。
- 電磁式の圧力増幅器(5)が、入口開口(17)を介して圧力室(14)に通じている入口通路(16)を有している、請求項4記載の装置。
- 圧力室(14)が出口(18)を有しており、該出口(18)が、燃料噴射弁(1)の入口通路(8)と流れ接続されている、請求項5記載の装置。
- 入口通路(16)から圧力室(14)への流れ接続が閉鎖可能であり、圧力室(14)内および該圧力室(14)の出口(18)の下流側での圧力増幅が、ピストン(15)の軸線方向のストロークによって達成可能である、請求項6記載の装置。
- 入口通路(16)から圧力室(14)への流れ接続が、前記入口通路(16)内の別体の弁によってか、またはピストン(15)によってか、または該ピストン(15)とプランジャ(11)との協働により閉鎖可能である、請求項7記載の装置。
