Abstract

A suspension mount for fuel-injection systems is used to connect a fuel injector to a fuel distributor. A connecting body having an accommodation space is provided, a fuel connector of the fuel injector being able to be disposed at least partially in the accommodation space. In addition, a joining body is provided that is disposed, at least in sections, partially in at least one recess of the connecting body, the recess being connected to the accommodation space, and on which the fuel connector is able to be supported along a longitudinal axis of the accommodation space. The joining body also has an elastically deformable element, the elastically deformable element being disposed in such a way that the joining body permits elastic support of the fuel connector on the connecting body at least along the longitudinal axis. A fuel-injection system having such a suspension mount is also indicated.

First claim

What is claimed is:

1. A fuel-injection system, comprising:
at least one fuel-conducting component;
at least one fuel injector; and
at least one suspension mount, the fuel injector being suspended from the fuel-conducting component via the suspension mount, wherein the suspension mount includes:
a connecting body including an accommodation space, a fuel connector of the fuel injector being able to be disposed at least partially in the accommodation space, and
a joining body situated partially in at least one recess of the connecting body, the recess being connected to the accommodation space, wherein:
the fuel connector is able to be supported on the joining body along a longitudinal axis of the accommodation space,
the joining body includes an elastically deformable element, the elastically deformable element is disposed in such a way that the joining body permits an elastic support of the fuel connector on the connecting body at least partially along the longitudinal axis,
the joining body includes a retaining element on a fuel-connector side, the fuel connector acts on the elastically deformable element of the joining body via the retaining element on the fuel-connector side, and
the retaining element on the fuel-connector side and the elastically deformable element are separate parts and are together inserted in a cutout of the fuel connector.

2. The fuel-injection system as recited in claim 1 , wherein the elastically deformable element is disposed in such a way that the joining body permits elastic support of the fuel connector on the connecting body along the longitudinal axis.

3. The fuel-injection system as recited in claim 1 , wherein the elastically deformable element is joined to the retaining element on the fuel-connector side.

4. The fuel-injection system as recited in claim 1 , wherein:
the joining body includes another retaining element on a connecting-body side,
the other retaining element on the connecting-body side is disposed partially in the recess of the connecting body, and
the elastically deformable element is supported on the connecting body via the other retaining element on the connecting-body side.

5. The fuel-injection system as recited in 4 , wherein the elastically deformable element is joined to the other retaining element on the connecting-body side.

6. The fuel-injection system as recited in claim 1 , wherein the elastically deformable element includes at least one of a disk-shaped element, an annular disk-shaped element, and a perforated element.

7. The fuel-injection system as recited in claim 1 , wherein the joining body is formed as an annular joining body or a part-annular joining body.
