89-411 - 15 - Abstract of the Invention A fuel injector for use in an internal combustion engine is provided and comprises an injector body having a first portion with an inlet for communicating with a fuel source, a second portion having an outlet for ejecting fuel from the body, and an inner passageway which communicates with the inlet and the outlet. A fuel valve is located within the inner passageway for controlling fuel ejection from the outlet. A silicon nozzle is positioned adjacent to the second portion for metering and dispersing fuel as it is ejected from the outlet. A retainer is connected to the injector body for retaining the nozzle against the second portion. The retainer includes a side portion and a base portion extending at an angle relative to the side portion for applying a spring-biased force against the nozzle to retain the nozzle against the second portion, thereby substantially sealing the interface between the nozzle and the second portion from fuel leakage.
