    摘要: A fluid distributor rail for an injection system for mixture-compressing, externally ignited internal combustion engines for metering a highly pressurized fluid. The fluid distributor rail includes a base body, and at least one connector configured on the base body. The base body with the at least one connector configured on the base body is formed by single stage or multistage forging. At least one interior space of the base body and a hydraulic fluid passage which leads into the interior space via the at least one connector configured on the base body are formed on the base body by machining after the forging. At least one element for connection is formed at least in part by mechanical cold-forming on at least one connector configured on the base body.

    摘要: 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.

    摘要: A system, which in particular is used as a fuel injection system for high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each of the fuel injectors is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a retaining clip. The retaining clip has at least one clip section which is situated between an inner side of the cup and an outer side of the fuel injector. Furthermore, at least one damping composite element is provided, which is situated between the clip section of the retaining clip and the outer side of the fuel injector. The damping composite element has an elastically deformable damping layer. A decoupling is thus realized, which acts to damp vibrations and consequently to reduce noise.
