Abstract
A common rail fuel injector includes a control valve member unattached to, but trapped between, a push pin and a seat of an injector body. The push pin has a head that includes a contact surface and a crown that includes a stop surface. An air gap surface of an armature is located between a top of the head and the stop surface of the crown when the contact surface of the push pin is in contact with the armature. The stop surface of the crown is located between an air gap plane of a stator assembly and the air gap surface of the armature. The push pin, the armature and the control valve member are movable among a rest configuration, an injection configuration, and an over travel configuration.
