Abstract
A diesel fuel injector having two separate annular or annulus-to-annulus dumps for providing a variable and a fixed orifice rapidly and controllably terminating injection and for controlling the impact velocity of the injector's intensifier piston against a mating stop. The injector further includes a middle chamber that is always connected to a low pressure vent to permit the collection and diversion of leakage fuel away from the middle chamber. The intensifier piston includes an upper member that is received within a stepped bore. The intensifier piston is loosely received within a lower member to permit relative motion therebetween for preventing the gall-up of the intensifier piston against the walls of the cooperating stepped bore.
