ABSTRACT:
An injector body defines a fuel pressurization chamber, a spill passage, a stop volume and a nozzle outlet. Positioned within the injector body is a plunger which is movable between a retracted position and an advanced position. The plunger opens the spill passage to the fuel pressurization chamber over a portion of the distance between the retracted and advanced positions. The injector body also contains a needle valve member which includes a closing hydraulic surface that is exposed to fluid pressure in the stop volume. The stop volume is pressure coupled to the spill passage.
