Abstract

A mounting is provided for fuel injection systems, the mounting connecting a fuel injection valve to a fuel-conducting component, and having a connecting body and a connecting piece that are connected to one another. Inside the connecting body and the connecting piece there is configured a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated. An inner collar is configured on the connecting piece. In addition, an elastically deformable element is provided. The elastically deformable element is supported at least indirectly on the inner collar of the connecting piece. In addition, the fuel connector is supported at least indirectly on the elastically deformable element. In addition, a fuel injection system having such a mounting is described.

First claim

What is claimed is:

1. A mounting for a fuel injection system for connecting a fuel injection valve to a fuel-conducting component, comprising:
a connecting piece, there being provided inside the connecting piece a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated, and an inner collar is configured on the connecting piece, wherein an elastically deformable element is provided, and the elastically deformable element is supported at least indirectly on the inner collar of the connecting piece, and the fuel connector is supported at least indirectly on the elastically deformable element;
wherein an annular supporting element is provided, and the elastically deformable element is supported on the inner collar of the connecting piece by the annular supporting element.

2. The mounting of claim 1 , wherein the annular support element has an annular opening in which the elastically deformable element is at least partly set, and/or the elastically deformable element is configured as an annular elastically deformable element.

3. The mounting of claim 2 , wherein the annular opening of the annular support element is made inwardly open.

4. A mounting for a fuel injection system for connecting a fuel injection valve to a fuel-conducting component, comprising:
a connecting piece, there being provided inside the connecting piece a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated, and an inner collar is configured on the connecting piece, wherein an elastically deformable element is provided, and the elastically deformable element is supported at least indirectly on the inner collar of the connecting piece, and the fuel connector is supported at least indirectly on the elastically deformable element;
wherein a support surface is configured on the fuel connector or on an element connected to the fuel connector, and an annular angled element is provided that has an L-shaped profile in which the elastically deformable element is at least partly set, and the fuel connector is supported on the elastically deformable element at least via the annular angled element.

5. The mounting of claim 4 , wherein the annular angled element lies against an outer side of the fuel connector.

6. The mounting of claim 4 , wherein the element connected to the fuel connector is connected to the fuel connector with a material fit.

7. A mounting for a fuel injection system for connecting a fuel injection valve to a fuel-conducting component, comprising:
a connecting piece, there being provided inside the connecting piece a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated, and an inner collar is configured on the connecting piece, wherein an elastically deformable element is provided, and the elastically deformable element is supported at least indirectly on the inner collar of the connecting piece, and the fuel connector is supported at least indirectly on the elastically deformable element;
wherein a U-shaped connecting clip is provided, and the connecting piece is connected to a connecting body of the fuel-conducting component via the U-shaped connecting clip, and the connecting body has on its outer side at least one opening, and the connecting piece has on its inner side at least one opening that is allocated to the opening of the connecting body, and the U-shaped connecting clip engages in the at least one opening of the connecting body and in the at least one opening of the connecting piece, and the U-shaped connecting clip is oriented at least approximately perpendicular to a longitudinal axis of the receptacle space.

8. A fuel injection system for mixture-compressing externally ignited internal combustion engines, comprising:
at least one fuel-conducting component;
at least one fuel injection valve; and
at least one mounting;
wherein the fuel injection valve is mounted on the fuel-conducting component via the mounting,
wherein the mounting includes a connecting piece, there being provided inside the connecting piece a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated, and an inner collar is configured on the connecting piece, wherein an elastically deformable element is provided, and the elastically deformable element is supported at least indirectly on the inner collar of the connecting piece, and the fuel connector is supported at least indirectly on the elastically deformable element, and
wherein an annular supporting element is provided, and the elastically deformable element is supported on the inner collar of the connecting piece by the annular supporting element.
