Abstract

Die vorliegende Erfindung zeigt einen Hochdruckinjektor mit folgenden Baugruppen: eine Injektoreinheit (1), eine Antriebseinheit (2) zum Antrieb der Injektoreinheit (1), vorzugsweise einer Hochdruckspeichereinheit (3) zur Versorgung der Injektoreinheit (1) mit Kraftstoff und ein Hochdruckanschluß (4). Dabei ist vorgesehen, dass der Hochdruckinjektor ein Gehäuse (5) aufweist, in welchem mehrere der genannten Baugruppen in Längsrichtung des Injektors hintereinander angeordnet sind, wobei das Gehäuse (5) zumindest eine der genannten Baugruppen, insbesondere die Antriebseinheit (2) und/oder die Hochdruckspeichereinheit (3), komplett umhüllt. Der Hochdruckinjektor mit Injektoreinheit kann in allen Arten von Verbrennungsmotoren, vorzugsweise Dieselmotoren verwendet werden.
