Abstract
A fuel injection nozzle assembly for the injection of fuel under pressure into a combustion chamber of an internal combustion engine. A nozzle body has formed therein a fuel inlet, a storage chamber and spray orifices for discharging pressurized fuel from the storage chamber. Disposed in the storage chamber is a needle valve for opening and closing the spray orifices and a check valve for admitting a metered amount of pressurized fuel into the storage chamber. The needle valve has formed therein a blind hole in which is slidably mounted a stem extending from a cylindrical section of a check valve and an axial passageway is formed through the stem.
