    Abstract: A fluid distributor. The fluid distributor includes a base body, a high pressure output, and a connecting piece which is joined to the base body and is used for the high pressure output. The base body is formed by a forging operation. An interior space of the base body is formed at the base body by a machining operation after the forging operation. The connecting piece is processed by a machining operation. A holding element is provided, that, as a result of the machining operation, an accommodating opening, which leads from an outer side of the connecting piece through a wall of the connecting piece and is used for at least partially accommodating the holding element, and an accommodating space, into which, during assembly, a connector of an injector is at least partially insertable in a mounting direction, are formed at the connecting piece.

  • Patent number: 10041460
    Abstract: 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.
