摘要： A fuel injector assembly with a fuel injector and a coupling device is disclosed. The coupling device includes a fuel injector cup, a plate element, one or more screws and a wing clip. The plate element includes at least one through-hole for fixedly coupling the fuel injector cup with the plate element by the screw or screws respectively, so that the fuel injector cup, the plate element and the screw(s) are positionally fixed with respect to each other. The wing clip is arranged at least partly around the fuel injector and extends outward in a radial direction such that the screw or screws, respectively, are operable to block a movement of the fuel injector relative to the plate element in a first direction of the central longitudinal axis by mechanical interaction with the wing clip.

摘要： In a fuel injection valve support structure which can apply a substantially constant set load, the fuel injection valve has first and second load receiving portions, the first load receiving portion being supported on the engine, the second load receiving portion being supported on an elastic support member which receives a set load from a fuel supply cap. The elastic support member includes a base plate placed on the second load receiving portion, and an elastic piece curving rearward from one end toward the other end of the base plate, with an apex portion in pressure contact with the cap, the base plate has a portion overhanging from the second load receiving portion and supporting a tip end portion of the elastic piece. The overhang portion starts bending when a load the overhang portion receives from the cap through the elastic piece reaches or exceeds a predetermined value.

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.

摘要： An adjustable racing injector injects fuel by carrying out an opening and closing of a fuel orifice in a valve seat. The fuel orifice is controlled by a signal, typically provided by an engine control unit, which energizes a magnetic circuit including coil which in turn will effect movement of a needle. The adjustable racing injector is field reconfigurable and may be provided as discrete components, or may be provided as an assembly together with a collection of replaceable components that are designed to controllably alter the performance of an engine to which the injector is attached. All of the performance components may be readily replaced in the field, while still obtaining repeatable performance across a plurality of injectors.
