  • Solenoid Actuator And Fuel Injector Using Same
    Publication number: 20130248612
    Abstract: Starting and ending an injection event are accomplished by respectively energizing and de-energizing a solenoid actuator to move an armature assembly with respect to a stator. The stator is protected from impact damage by maintaining the armature assembly out of contact with the stator. The inducement of residual magnetism in the armature assembly is reduced by stopping the armature assembly at a large radius outside of the magnetic flux circuit through the stator and soft magnetic armature of the armature assembly, when the solenoid actuator is energized.
