Abstract

Kraftstoffeinspritzventil für Brennkraftmaschinen mit einem eine Achse (8) aufweisenden Ventilkörper (3), der mittels einer Spannhülse (7) in axialer Richtung gegen einen Ventilhaltekörper (1) vorgespannt ist. Im Ventilkörper (3) ist wenigstens eine Einspritzöffnung (20) zur Einbringung von Kraftstoff in einen Brennraum ausgebildet und am Ventilkörper (3) verläuft eine Ringschulter (30), an der die Spannhülse (7) mit einer an ihrer Innenseite ausgebildeten ringscheibenförmigen Anlageschulter (32) zur Anlage kommt und dabei die axiale Kraft überträgt. Die Anlageschulter (32) und/oder die Ringschulter (30) sind so angeschrägt, dass die Axialkraft im achsnahen Bereich der Anlageschulter (32) auf die Ringschulter (30) des Ventilkörpers (3) übertragen wird (Figur 1).
