ABSTRACT:
A fuel injector is described that includes a polymeric housing, pole piece, filter assembly, coil assembly, spring member, armature assembly and metering assembly. The polymeric housing has a passageway extending between an inlet and an outlet along a longitudinal axis. The pole piece is disposed in the passageway. The metering assembly is secured to the polymeric housing proximate the outlet. The metering assembly has a seat molded to a polymeric support member. The polymeric support member may be cylindrical and bonded to the polymeric bore proximate the outlet. A method of operating the fuel injector is described.
