Abstract

Die Erfindung betrifft ein Einspritzsystem für Kraftstoffeinspritzanlagen mit einem mit einer Hochdruckanschlußstelle (2) verbundenen Injektor, wobei die Hochdruckanschlußstelle (2) und der Injektor über mindestens eine mit einer Überwurfmutter (4) versehene Schraubverbindung (3) miteinander verbunden sind. Um ein Einspritzsystem bereitzustellen, bei dem die Schraubverbindung (3) auch unter Druck gefahrlos geöffnet werden kann, wird erfindungsgemäß vorgeschlagen, daß im Bereich der Schraubverbindung (3) mindestens eine Druckbegrenzungseinrichtung ausgebildet ist.
