Abstract:
A solenoid assembly for use in a fuel injector having an injection port comprising:a middle body section having a first end, a second end and a cavity therein;an armature having a first end, a second end and a fuel passage therethrough;a solenoid mounted within the cavity of the middle body section and having a first end, a second end and windings adapted to exert an axial force on the armature;the middle body section, the armature and the solenoid adapted to operate in each of two positions, a first position wherein a first pintle is attached to the armature and the first ends of the armature, middle body section and the solenoid are proximal to the injection port and a second position wherein a second pintle is attached to the armature and the second ends of the armature, middle body section and the solenoid are proximal the injection port such that in the first position, the solenoid exerts a force on the first pintle in one axial direction and in the second position, the soleniod exerts a force on the second pintle in the opposite axial direction.
