Abstract

Bei einer Kraftstoff-Einspritzdüse für eine Verbrennungskraftmaschine, mit einem Düsenkörper (10), einer Düsennadel (12), die in dem Düsenkörper verschiebbar zwischen einer geschlossenen Stel lung ist, in der sie an einem Dichtsitz (16) anliegt, und einer geöffneten Stellung, in der sie in Richtung zum Verbrennungsraum hin von dem Dichtsitz abgehoben ist, einer Druckkammer (24), die mit einem Kraftstoff-Zulauf (26) in Verbindung steht, einer Steuerkammer (42), die von einem Steuerventil (46) gesteuert mit dem Kraftstoff-Zulauf in Verbindung steht, und einer Druckstange (40), die mit der Düsennadel verbunden ist und in die Steuerkammer hineinragt, soll zuverlässig eine Schliesskraft bereitgestellt werden, die eine im Bereich des Dichtsitzes erzeugte Öffnungskraft überwindet. Zu diesem Zweck ist vorgesehen, dass die Druckstange mit einem Rückstellkolben (28) versehen ist, der die Druckkammer (24) auf der vom Dichtsitz abgewandten Seite abschliesst, dass der Aussendurchmesser des Rückstellkolbens grösser ist als der Durchmesser des Dichtsitzes (16) und dass die Fläche, die sich aus der Differenz zwischen der Querschnittsfläche des Rückstellkolbens (28) und der von dem Dichtsitz (16) eingeschlossenen Fläche ergibt, kleiner ist als die Querschnittsfläche der Druckstange.
