ABSTRACT:
A solenoid actuated fuel injector includes an elongated ferromagnetic inlet tube having a major outside diameter portion and a reduced outside diameter portion and a step between the major and reduced outside diameter portions. A two-ended non-magnetic shell including an elongated tubular portion and a valve body shell engaging portion is fittable over the inlet tube reduced diameter portion and abuts the step in the inlet tube at one end. A coil is mountable around the elongated tubular portion of the non-magnetic shell and seated on the valve body shell engaging portion. The coil has a length shorter than the elongated tubular portion, at at least one circumferential point of the coil, allowing the inlet tube to be welded to the non-magnetic shell upon rotation relative to the coil without having to move the coil longitudinally.
