Abstract (en)
1. Fuel injection nozzle for, in particular, self-ignition-type internal-combustion engines, comprising a nozzle housing (10, 62) which, in the installed condition, protrudes from an installation hole (56) of the engine casing (34) at least over a part of its length and the protruding area of which is provided with a central threaded stub (20) for connecting a fuel line, characterized by the following features : a) a protective cap (40, 60), which is known per se, is constructed as an inherently rigid component which is at least approximately adapted to the shape of the area of the nozzle housing (10, 62) protruding from the engine casing (34) and consists of a material having spring-elastic properties, preferably plastic ; b) the protective cap (40, 60) exhibits at its side facing away from the engine casing an opening through which the threaded stub (20) of the nozzle housing (10, 62) penetrates when the protective cap (40, 60) is pushed onto the nozzle housing (10, 62) ; c) the protective cap (40, 60) also exhibits at its side facing away from the engine casing elastically deflectable wall sections (43, 74) which point towards the opening and which are separated from one another by slots and which lockingly engage behind a shoulder, pointing towards the engine casing, of the threaded stub (20).

Kraftstoff-Einspritzdüse für Brennkraftmaschinen, mit einer Schutzkappe (40, 60), welche die aus dem Maschinengehäuse herausragenden Teile (10, 12, 62) der Einspritzdüse mindestens teilweise übergreift. Die Schutzkappe (40, 60) ist erfindungsgemäß als ein der Form der umgriffenen Teile (10, 12, 62) mindestens annähernd angepaßtes, eigensteifes Bauteil ausgebildet und unverlierbar an einem dieser Teile festgehalten. Dadurch ist mit einfachen und billigen Mitteln das Korrosionsproblem der von der Schutzkappe umgriffenen Teile gelöst und außerdem kann die Schutzkappe als Informationsträger für die Einspritzdüse dienen, so daß ein Einrollen der Düsenhalterbeschriftung und gegebenenfalls eine Farbkennzeichnung am Düsenhalter entfällt.
