Embodiment Construction

[0040] figure 1 A fuel injection system 1 with a fuel guide part 2 and an assembly 3 for connecting a fuel injection valve 5 ( figure 2 ) of the joint piece 4 is connected to the cup seat 6 of the fuel guide part 2 . The fuel guiding part 2 here has a tubular base body 7 and a cup 6 , wherein, in addition to the cup 6 , further cups are fastened to the tubular base 7 , preferably along the axial extension of the tubular base 7 superior. To simplify the illustration, only a section of the tubular base body 7 is shown here, wherein the tubular base body 7 extends along its axis 8 over a sufficient length.

[0041] In this exemplary embodiment, the tubular main body 7 can be part of the fuel-carrying component 2 designed as a fuel distributor 2 , in particular a fuel distribution rail 2 . The interior space 9 of the tubular base body 7 then serves as a fuel accumulator in order to store fuel under high pressure and to distribute the fuel via a corresponding number of cups 6 t...

Abstract

The invention relates to an assembly (3) for connecting a connection part (4) of a fuel injection valve (5) to a cup (6) of a fuel guide part (2), wherein a connecting clip (15) is provided. The connecting clip (15) connects the connection piece (4) of the fuel injection valve (5) to the cup (6) in the assembled state. Here, at the contact contour (39) provided on the connection part (4) and the contact contour (33) provided on the connection clamp (15) in the assembled state between the connection part (4) and the connection Contact occurs between the clips (15), and the contact contours are configured in such a way that they match each other so that a support (45) of the connection part (4) on the connection clip (15) is ensured, which allows the connection part (4) to The longitudinal axis (24) of the cup (6) pivots.

Description

technical field [0001] The invention relates to an assembly for connecting a fitting part of a fuel injection valve to a cup seat of a fuel guide part and a fuel injection device having a fuel guide part, a fuel injection valve and such an assembly for connecting The fuel injection valve is connected to the cup of the fuel guide part. The invention relates in particular to the field of fuel injection devices for hybrid compression externally ignited internal combustion engines. Background technique [0002] A fuel injection device for a fuel injection system of an internal combustion engine is known from DE 10 2005 009 740 A1. The fuel injection device has a fuel injection valve, a receiving bore for receiving the fuel injection valve in the cylinder head, and a fuel distribution line with a connecting piece in which the fuel injection valve is inserted partially overlapping. The connecting body is arranged in such a way that the fuel injection valve is held on the connect...
