Abstract

Eine Kraftstoffeinspritzdüse für Brennkraftmaschinen, insbe­ sondere Pumpedüse, mit einem Gehäuse (2), in dem elektrische Sensoren und/oder Stelleinrichtungen, insbesondere ein elek­ trischer Nadelhubsensor für die Düsennadel und/oder ein elektromagnetischer Mengensteller untergebracht sind, und mit elektrischen, zum Kontaktieren aus dem Gehäuse geführten Anschlußleitungen (10, 11) für die Sensoren und/oder Stell­ einrichtungen. A fuel injector for internal combustion engines, esp special pump nozzle, with a housing (2) in which electrical Sensors and / or control devices, in particular an elec tric needle stroke sensor for the nozzle needle and / or electromagnetic volume control are housed, and with electrical ones that come out of the housing for contacting Connection lines (10, 11) for the sensors and / or actuators facilities.

Um eine einfache, servicefreundliche und trotz der rauhen Umgebungsbedingungen sichere Kontaktierung der Anschluß­ leitungen zu ermöglichen, ist vorgesehen, daß in einem zum Niederspannen der Düse an dem Zylinderkopf (4) angeordneten Flansch (3) des Düsengehäuses (2) zumindest eine zur Düsen­ achse (a) im wesentlichen parallele Durchgangsbohrung (8) ausgebildet ist, in welche die Enden der Anschlußleitungen (10, 11) geführt und in der Durchgangsbohrung und/oder unter Zwischenschaltung eines Steckerteils (14, 14′) außerhalb der Bohrung (8) mit Steckkontakten (22, 36) versehen sind. To be a simple, service friendly and despite the rough Ambient conditions secure connection of the connection To enable lines, it is provided that in a to Lower the nozzle on the cylinder head (4) Flange (3) of the nozzle housing (2) at least one to the nozzle axis (a) essentially parallel through hole (8) is formed, in which the ends of the connecting lines (10, 11) guided and in the through hole and / or under Interposition of a plug part (14, 14 ') outside of Bore (8) are provided with plug contacts (22, 36).
