ELECTROMAGNETIC UNIT FUEL INJECTOR WITH PISTON ASSIST SOLENOID ACTUATED CONTROL VALVE Abstract of the Disclosure An electromagnetic unit fuel injector includes a pump assembly having an external actuated plunger reciprocable in a bushing with flow therefrom during a pump stroke being directed to a fuel injection nozzle of the assembly. Fuel flow from the pump can also flow through a passage means, containing a normally open, substantially pressure-balanced control valve actuated by a solenoid assembly in the valve closing direction to block drain slow during a pump stroke, as desired. A piston, actuated by discharge fuel pressure is operatively connected to the control valve to assist the solenoid in holding the control valve in a closed position.
