Abstract
Description
Die Erfindung betrifft einen Injektor für eine Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to an injector for a fuel injection device an internal combustion engine according to the preamble of claim 1.
Bei heutigen Dieseleinspritzeinrichtungen und insbesondere im Rahmen der Common-Rail-Technologie stellt sich oft das Problem, daß mehrere axial hintereinander angeordnete Bauteile mit hoher Anpreßkraft verspannt werden müssen. Hierzu wird eine Düsenspannmutter verwendet, die entsprechend lang sein muß. Wegen des beengten Bauraums im Bereich der Einspritzdüse kann die Düsenspannmutter nur eine relativ geringe Wandstärke aufweisen und ist dementsprechend weich, abgesehen davon, daß ein Wechsel der Einspritzdüsen zu einem Aus- und Einbau auch der übrigen, mit der Düsenspannmutter verspannten Bauteile führt.at today's diesel injection devices and especially in the frame Common rail technology often raises the problem that several components clamped axially one behind the other with high contact pressure Need to become. For this becomes a nozzle clamp nut used, which must be correspondingly long. Because of the cramped installation space in the area of the injection nozzle can the nozzle clamping nut only have a relatively small wall thickness and is accordingly soft, apart from being a change of the injectors for removal and installation of the rest, with the nozzle clamping nut clamped components leads.
Aufgabe der Erfindung ist es, einen Injektor nach dem Oberbegriff des Anspruchs 1 zu schaffen, der es ermöglicht, mit einer kurzen Düsenspannmutter auszukommen.task the invention is an injector according to the preamble of the claim 1, which enables with a short nozzle clamping nut get along.
Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This Task becomes according to the characterizing part of the claim 1 solved.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further Embodiments of the invention are the following description and the dependent claims refer to.
Die Erfindung wird nachstehend anhand eines in der beigefügten Abbildung dargestellten Ausführungsbeispiels näher erläutert, wobei die Abbildung ausschnittweise einen Injektor für eine Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine teilweise im Axialschnitt zeigt.The Invention is illustrated below using one in the accompanying figure illustrated embodiment explained in more detail, whereby the illustration excerpts of an injector for a fuel injection device shows an internal combustion engine partially in axial section.
