Abstract

Es wird ein Einspritzventil mit einem Gehäuse (2), einer Spannmutter (1) und einem Düsenkörper (3) beschrieben, wobei die Spannmutter den Düsenkörper (3) gegen das Gehäuse (2) vorspannt. Die Flächenpaarung (9, 10) zwischen der Spannmutter (1) und dem Düsenkörper (3) sind in der Weise optimiert, dass eine hohe Vorspannkraft ohne Beschädigung der Spannmutter auf den Düsenkörper ausgeübt wird. Zugleich wird der Druckraum (5) im Düsenkörper durch die Vorspannkraft optimal unterstützt, so dass ein hochdruckfester Düsenkörper bereitgestellt wird.
