Description
請求項1の特徴部に記載のように構成された本発明による燃料噴射弁には、公知のものに比べて次のような利点がある。すなわち本発明による燃料噴射弁では、可動子が、相応に配置されたばねによって振動するように弁ニードルに支承されており、従って開放動作時には前行程を行うことができ、しかも可動子は閉鎖時に弁ニードルに対して振動することができ、これによって弁ニードルのさらなる別の開放行程を回避することができる。
次に図面を参照しながら本発明の1実施例を説明する。
図2は、図1に示された本発明による燃料噴射弁において一点鎖線で示された範囲IIを拡大して示す図である。
次に図面を参照しながら本発明の実施例を説明する。なお、すべての図面において同一部材には同一符号が使用されている。
Claims (10)
- 内燃機関の燃焼室に燃料を直接噴射する燃料噴射弁(1)であって、マグネットコイル(10)と共働する可動子(20)と、弁ニードル(3)とが設けられていて、該弁ニードル(3)に可動子(20)が可動に配置されており、さらに弁ニードル(3)に弁閉鎖体(4)が設けられていて、該弁閉鎖体(4)が弁座面(6)と一緒にシール座を形成している形式のものにおいて、
