ABSTRACT:
A distortion control ring disposed and connected between a fuel injector body and a clamping device. The distortion control ring is utilized as an intermediary for transmitting a static clamping load from the clamping device to the fuel injector body. The distortion control ring includes a cylindrical shaped main body having a bore extending therethrough between an upper surface and a lower surface. The upper surface of the main body being adapted for mounting a return spring thereon. The lower surface having an annular portion for contacting the fuel injector body. A radial flange is formed on the distortion control ring adjacent to the main body for contacting the clamping device and receiving the static clamping load. The clamping device engages the radial flange at a distance radially outward of where the lower surface of the main body contacts the fuel injector body. This geometric relationship between the radial flange and the lower surface of the main body transfers the static clamping load to a central portion of the fuel injector body. By transferring the static clamping load to a more central portion of the fuel injector body there is a corresponding reduction in the failure rate of fuel injector units.
