Abstract
A cam driven fuel injector comprising: a body defining a bore; a driven or pumping piston reciprocatively situated with the bore; a metering piston reciprocatively positioned within the bore remote from the pumping piston; and a metering chamber defined in the bore below the metering piston. A spring is situated within a cavity or spring cage remote from the bore and a nozzle extends into the spring cage in biasing engagement with the spring to urge it to a closed position during non-injecting periods. The injector further including means for dumping the fuel within the metering chamber to the supply through the spring cage in correspondence with the motion of the metering piston; and for stabilizing the pressure force exerted on the nozzle, during the dumping portion of operation, by the fuel within the spring cage with the pressure force exerted on the nozzle.
