Abstract
An electromagnetic unit fuel injector includes a pump assembly having an externally actuated plunger reciprocable in a bushing means to define a variable volume pump chamber and a pressure actuated fuel injection nozzle. Fuel, at a suitable supply pressure, in a supply chamber is adapted to be in flow communication with the pump chamber by suitable passage means having a normally open, electromagnetic valve means controlling flow through a first portion thereof and a normally open servo control valve means, including a servo control valve and piston, controlling flow through a second portion thereof. Fuel injection during a pump stroke of the plunger is initiated by the controlled energization of the electromagnetic valve means to block return flow of fuel so as to effect closure of the servo control valve means whereby the fuel pressure can be further intensified to effect operation of the injection nozzle.
