CLAMP FOR AN INTERNAL COMBUSTION ENGINE FUEL INJECTOR

摘要

A fuel injector clamp takes the form of a generally ovalshaped ring manufactured from pipe so that the side walls on the minor axis enclose flats on opposite sides of the injector body and the end walls on the major axis each encircle a respective fixing bolt. The end walls encircle more than 180 degrees of the circumference of the bolt. The side walls adjacent each end are pinched inwards towards one another, but are not fully brought together. Encirclement of the fixing bolts in this way serves to increase the contact area between the bolts and clamp to ensure improved clamping, and also produces an inherent resistance to spreading of the side walls. The lower edges of the side walls are each formed with a pair of indentations so that the portion therebetween is arcuate and forms a point contact with a respective bearing shoulder on the injector body. These indentations are formed by deformation of the edges of the side wall so as to avoid machining. Thus a tiltable clamp can be provided in a simple manner from a uniform width of pipe without involving any material waste.
