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 system for injection systems serves to connect a fuel injection valve to a fluid-conveying component. In the installed state, a connector piece of the metering valve is inserted at least partly into a receiving space of a connector body of the component. A support part is disposed on the connector piece. The connector piece of the fuel injection valve is mounted on the connector body in the installed state via the support part, a decoupling element, and a fastening body. The abutment body is retained by the fastening body in such a way that the abutment body is movable radially with respect to the longitudinal axis at least in the context of installation relative to the fastening body.

摘要： A bearing bush is for a holder, which is for fastening a component, particularly of a fuel distributor, to an add-on structure. The bearing bush has an inner bush part, which is made of a metallic material, and an outer bush part, which is made of a metallic material, and an elastically deformable damping element. The outer bush part has a continuous recess, in which the inner bush part is situated. The damping element is situated between the inner bush part and the outer bush part. A holder having such a bearing bush is also specified. In addition, a fuel-injection system having a fuel distributor and at least one holder is specified, which is used for fastening the fuel distributor on an internal combustion engine.

摘要： A suspension for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. A connecting body having a receiving space is provided for this purpose. The connecting body has an opening, via which a fuel fitting of the fuel injector is insertible at least partially into the receiving space of the connecting body. Furthermore, an annular element and an elastically deformable element are provided. Fuel fitting is supported via the annular element and the elastically deformable element along an axis of the receiving space of the connecting body. A fuel injection system having such a suspension is also indicated. The suspension allows for a soft coupling of the fuel injector to the fuel-carrying component at a desired target stiffness.

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.
