Control valve having a solenoid with a permanent magnet for a fuel injector

A control valve comprising:

• a valve body with a centerline and defining an inlet passage separated from an outlet passage by a valve seat;
• a solenoid attached to said valve body, and including a coil and an armature, and a portion of said armature being a permanent magnet;
• a polarity of said permanent magnet being oriented such that said armature is pushed away from said coil when said solenoid is energized;
• a valve member positioned in said valve body and attached to said armature, and being movable between an open position in which said inlet passage is open to said outlet passage, and a closed position in which said inlet passage is closed to said outlet passage;
• and
• said armature being positioned between said coil and said valve member along said centerline.

A fuel injector comprising;

• an injector body defining a nozzle outlet and a cartridge opening, and further defining a spill passage and a return passage that open into said cartridge opening;
• a cartridge control valve with a valve body and being received in said cartridge opening and attached to said injector body;
• said valve body defining an inlet passage separated from an outlet passage by a valve seat, and said inlet passage opening to said spill passage, and said outlet passage opening to said return passage;
• a solenoid attached to said valve body, and including a coil and an armature, and a portion of said armature being a permanent magnet;
• a polarity of said permanent magnet being oriented such that said armature is pushed away from said coil when said solenoid is energized;
• and
• a valve member positioned in said valve body and attached to said armature, and being movable between an open position in which said inlet passage is open to said outlet passage, and a closed position in which said inlet passage is closed to said outlet passage.
