ABSTRACT:
An electrically-controlled fuel injector comprising a balanced pressure sl valve that alternately connects an injector plunger control chamber to fuel supply pressure or drain pressure, thereby putting the injector plunger in the closed mode or the injection mode. Fuel pressure is utilized so that the spool valve can be operated (moved) by a relatively small size solenoid. This injector is particularly designed for use in electronic fuel injection systems.
