Abstract

Die vorliegende Erfindung betrifft ein Kraftstoffeinspritzventil mit Injektormodulen (1, 5, 6, 7, 8), welche in Axialrichtung übereinander angeordnet sind, so dass sich zwischen den Injektormodulen ebene Dichtflächen ergeben. Die Injektormodule sind mittels eines Vorspannmittels (10) gegeneinander verspannt, so dass eine Abdichtung aufgrund einer hohen Flächenpressung zwischen den Dichtflächen (D) der Injektormodule erfolgt. Hierbei ist ein Abstand zwischen einem Zulaufkanal (9) zum Zuführen von Kraftstoff unter Hochdruck und einem Führungskanal (3) kleiner als ein Abstand zwischen dem Zulaufkanal (9) und einem äußeren Rand der Injektormodule.

The present invention relates to a fuel injection valve with injector modules (1, 5, 6, 7, 8) which are arranged one above the other in the axial direction, so that flat sealing surfaces result between the injector modules. The injector modules are braced against one another by means of a pretensioning means (10), so that sealing takes place due to a high surface pressure between the sealing surfaces (D) of the injector modules. A distance between an inlet channel (9) for supplying fuel under high pressure and a guide channel (3) is smaller than a distance between the inlet channel (9) and an outer edge of the injector modules.
