Abstract
The present invention relates to a fuel injector for an internal combustion engine, which utilizes a fuel supply control valve and pilot or servo-valve to control the supply and drain of fuel to and from a main fuel chamber. More particularly, the pilot valve separates and isolates the main fuel chamber from the control valve which controls the fuel supply to the main fuel chamber. In this manner, the control valve can operate without interference from the fuel pressure fluctuations created in the main fuel chamber by a reciprocating plunger.
