Abstract
A non-metallic cylindrical shell is fitted to the exterior of a metallic valve body portion of a solenoid-operated fuel injector to cover otherwise exposed metal that exists between a lower O-ring seal proximate the nozzle and a non-metallic overmold that covers the solenoid and an adjoining portion of the valve body. The shell and the cover come together at a joint where they mutually axially overlap in such a manner that assures both coverage of the exposed metal and retention of the shell on the valve body for the full tolerance stack-up range of the various parts when assembled.
