Abstract

A fuel injector, for use on an internal combustion engine includes a tubular injector body defining an axial fuel passage, disposed within the injector body is an armature, a solenoid assembly which includes a spool-like bobbin with a central through-bore and a wound wire coil A pole piece includes a tubular, cylindrical pole having, at its terminal end, a working surface. The cylindrical pole is configured for axial disposition within the central through-bore of the bobbin such that it is positioned with the working surface intermediate of the ends of the wire coil. An axially extending non-magnetic cylindrical tube has a first end received about the terminal end of the cylindrical pole and has a second end, disposed axially downstream of the working surface of the pole and of the central through-bore of the bobbin within axial fuel passage of the tubular injector body. The tubular member is configured to receive the armature therein, and includes a radially inwardly extending, annular bearing surface disposed intermediate of the first and the second ends for circumjacent, sliding support of said armature therein. The second end of the non-magnetic tubular member may cooperate with the injector tubular body to forma a seal against fuel entry into the wound wire coil of the solenoid actuator.
