Locating pin

摘要

A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.

主权项

1. A fuel injector assembly, comprising:
a control valve body having a plurality of mating surfaces; a plurality of end caps, each end cap having a mating surface disposed to connect to a respective mating surface of the control valve body; a plurality of locating pins, each locating pin having a pin length and a pin diameter; a plurality of end cap locating holes formed into the mating surface of each end cap; and a plurality of control valve body locating holes formed into each mating surface of the control valve body; one of the plurality of end cap locating holes and the plurality of control valve body locating holes having a longitudinal axis, a first bore with a first diameter so as to allow for fastening to a locating pin, and a second bore with a second diameter larger than the first diameter, the second bore being on the longitudinal axis and proximate to its respective mating surface, the first bore being remote from its respective mating surface; and the other of the plurality of end cap locating holes and the plurality of control valve body locating holes having a third bore with a third diameter being at least as large as the pin diameter.
