Abstract
A clamping load distributor and top stop disposed and connecting between a fuel injector body and a clamping device. The clamping load distributor functions as an intermediary to transmit the static clamping load from the clamping device to the fuel injector body. The clamping load distributor includes a cylindrically shaped main body having a bore extending therethrough that is disposed adjacent a coupling return spring. A cap is connected to the cylindrically shaped main body and functions as a top stop for limiting the outward axial movement of a mechanical linkage. The restriction on axial movement creates a small gap between the moving mechanical parts to allow a coating of lubrication to be obtained. The main body having a pair of clamp receiving portions formed therein for receiving a clamping load. An annular ring is formed on the bottom side of clamping load distributor radially inward from the clamp receiving portions for contacting the upper deck of the fuel injector body. The geometric relationship of the clamping load distributor functions to transfer the static clamping load radially inward towards the fuel injector units center of mass. The transferring of the clamping load radially inward results in a significant decrease in the occurrence of timing plunger seizure within the fuel injector unit.
