ABSTRACT:
A fuel injection nozzle assembly includes a nozzle body and a compressible valve therein having a valve head that is normally in loaded abutment against a valve seat in the nozzle body to block the discharge of fuel therefrom, the compressible valve further including a stem extending from the valve head which is fixed at its opposite end to the valve body, the stem including a thin wall, tubular compressible stem portion next adjacent to the valve head and connected thereto by an annular shoulder, the compressible stem portion having an outside diameter substantially greater than the diameter of the valve head with the thin wall of the compressible stem portion being sized so that when fuel, in an annular fuel chamber in the nozzle body encircling the compressible stem portion, at a high fuel pressure acts on the annular shoulder, it will cause a reduction in the normal longitudinal extent of the compressible valve to effect unseating of the valve head from the valve seat and, when the fuel in the fuel chamber is at a reduced pressure, the valve head is seated against the valve seat.
