ABSTRACT:
A diesel fuel injection nozzle and holder assembly includes a tubular nozzle holder carrying a nozzle on one end and defining, in combination therewith, a storage chamber for receiving successive charges of fuel under pressure via a check valve mounted therein. A needle valve, complete with a stem, mounted in the storage chamber is urged by a first spring toward a position for closing spray orifices in the nozzle. Disposed opposite to the end of the needle valve stem, a yieldable abutment is biased by a second spring toward the stem and normally retained a preassigned distance away therefrom. When acted upon by each pressurized fuel charge trapped in the storage chamber, the needle valve is unseated to open the spray orifices against the force of the first spring if the fuel pressure is relatively low, and against the resultant of the forces of the first and second springs if the fuel pressure is higher.
