Description
これに対して、請求項1に記載した特徴を有する本発明による電磁石は、コイル支持体をディスク状(scheibenfoermig;円板状)に構成したことによって、マグネットコイルとマグネットアーマチャとの間の小さい間隔が得られ、これによって電磁石のダイナミズムが改善され、電磁石の構造的な大きさが縮小された、という利点が得られた。
本発明の実施例が図面に示されていて、以下に詳しく説明されている。図1には、電磁弁を備えた内燃機関のための燃料噴射装置が断面図で示され、図2には、電磁弁の電磁石が拡大して示され、図3には、図2に示した電磁石のコイル支持体及びコイル巻線を示している。
図1には例えば自動車の内燃機関のための燃料噴射装置が概略的に示されている。内燃機関は有利な形式で自己点火式の内燃機関であって、単数又は複数のシリンダを有している。この燃料噴射装置は例えば図1に示されているように、ポンプ・ノズルユニットとして構成されており、このポンプ・ノズルユニットは、内燃機関の各シリンダのための燃料高圧ポンプ10と燃料噴射弁12とを有している。これの各シリンダは1つの共通の構成ユニットを形成している。ポンプ・ノズルユニットには、燃料噴射を制御するための少なくとも1つの電磁弁56,60が配置されている。選択的に、燃料噴射装置は、ポンプ・管路ノズルユニットとして構成されていてもよい。このポンプ・管路ノズルユニットにおいては、内燃機関の各シリンダのためのそれぞれ1つの燃料高圧ポンプと燃料噴射弁とが設けられているが、この燃料高圧ポンプと燃料噴射弁とは互いに分離して配置されていて、液圧式の管路を介して互いに接続されていてもよい。ポンプ・管路・ノズルユニットの燃料高圧ポンプ又は燃料噴射弁には、燃料噴射ポンプを制御するための電磁弁が配置されている。さらに、燃料噴射装置はコモンレールシステムとして構成されていてもよい。このコモンレースシステムにおいては、燃料高圧ポンプによって燃料が蓄圧器に送られ、この蓄圧器は、内燃機関のシリンダに配置された各インジェクタに接続されていて、これらのインジェクタに、燃料噴射を制御するための各1つの電磁弁が配置されている。さらにまた燃料噴射装置は、燃料を高圧下で圧送する燃料噴射ポンプとして構成されていて、この燃料噴射ポンプに、内燃機関の各シリンダに配置された燃料噴射弁が接続されており、この場合、燃料噴射ポンプには、高圧発生及びひいては燃料噴射を制御するための電磁弁が配置されている。
