ABSTRACT:
In a fuel injection nozzle for an internal combustion engine with a fuel injection opening including a nozzle opening control needle with a body portion with discharge openings whose size depends on the axial displacement of the nozzle opening control needle and with means for limiting the axial displacement of the nozzle opening control needle, a hollow nozzle needle is disposed around the stem of the nozzle opening control needle and forms at its end a fuel control valve seat for controlling fuel flow to the fuel injection opening and a control space is provided at the end of the hollow nozzle needle opposite its valve seat which is in communication with a pressurized fuel supply for holding the hollow nozzle needle in a seated position but from which the pressure can be released to permit lifting of the hollow nozzle needle by pressurized fuel supplied to the seating area end of the hollow nozzle needle whereupon the pressurized fuel released through the fuel control valve displaces the nozzle opening control needle to open the discharge opening as permitted by limiting mechanism.
