Abstract

Eine Befestigungsvorrichtung zur Befestigung eines Brennstoffeinspritzventils (1) in einem Zylinderkopf (2) einer Brennkraftmaschine weist zumindest einen Niederhalter (11) auf, der an einer Stirnseite (12) des Zylinderkopfes (2) befestigt ist und das Brennstoffeinspritzventil (1) in einer Aufnahmebohrung (9) des Zylinderkopfes (2) fixiert. Der zumindest eine Niederhalter (11) stützt sich dabei auf einem an einem abströmseitigen Ende (6) des Brennstoffeinspritzventils (1) ausgebildeten Absatz (7) ab und umfasst das Brennstoffeinspritzventil (1) zumindest teilweise. Der Niederhalter (11) ist einstückig und in Form eines Niederhaltetopfes (17) ausgebildet.

Figure imgaf001
A fastening device for fastening a fuel injection valve (1) in a cylinder head (2) of an internal combustion engine has at least one hold-down device (11) which is fastened to an end face (12) of the cylinder head (2) and the fuel injection valve (1) in a receiving bore (11). 9) of the cylinder head (2) fixed. The at least one hold-down device (11) is supported on a shoulder (7) formed at a downstream end (6) of the fuel injection valve (1) and at least partially surrounds the fuel injection valve (1). The hold-down (11) is formed in one piece and in the form of a hold-down pot (17).
