Abstract

Bei einem Kraftstoffeinspritzventil mit einem Ventilkörper (10), einem darin ausgebildeten Steuerdruckraum (16), der an einer Seite von einem Betätigungsteil (14) für eine Düsennadel (12) verschlossen ist, die von dem Betätigungsteil gesteuert zwischen einer Schließstellung und einer Öffnungsstellung verschiebbar ist, einem Zulauf (18) zum Steuerdruckraum und mit einem Ablauf (20) aus dem Steuerdruckraum der von einem Steuerventil (24) gesteuert wird, soll ein Teilöffnungshub der Düsennadel ermöglicht werden, bei dem, die eingespritzte Kraftstoffmenge mit hoher Präzision dosiert wird. Zu diesem Zweck ist ein verschiebbarer Drosselkolben (32) vorgesehen, der in einer ersten Stellung einen Teilöffnungshub der Düsennadel aus der Schließstellung entgegen einem geringen Widerstand ermöglicht und in einer zweiten Stellung einen sich an den Teilöffnungshub anschließenden restlichen Öffnungshub der Düsennadel (12) in die Öffnungsstellung nur entgegen einem höheren Widerstand ermöglicht.
