  • Reverse acting nozzle valve and fuel injector using same
    Patent number: 6454189
    Abstract: A nozzle assembly includes a tip body having a lower end and defining a nozzle outlet. A needle sleeve is at least partially positioned in the tip body and includes a valve seat. A needle valve member is at least partially positioned within the needle sleeve, and is moveable between a closed position in contact with the valve seat and an open position out of contact with the valve seat. The needle valve member moves toward the lower end of the tip body when moving toward its open position. The nozzle assembly finds its preferred application in hydraulically-actuated fuel injectors having direct control needles.
