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.
