Date Mar. 28, 1996The fuel injection nozzle according to the present invention comprises a nozzle body provided with nozzle holes, a needle valve that opens and closes the nozzle holes, an armature that is mechanically linked with the needle valve and a stator that faces opposite the armature, so that, by displacing the stator with a micromotor, the lift quantity of the needle valve can be adjusted. In addition, a cover member that rotates slidably around the circumference of the nozzle body is provided and by causing this cover member to rotate with a micromotor, the opening area of the nozzle hole contributing to injection is varied. With these structural features, it becomes possible to intentionally achieve a desired injection pattern.

    • PCT No. PCT/DE95/00523 Sec. 371 Date Oct. 30, 1996 Sec. 102(e) Date Oct. 30, 1996 PCT Filed Apr. 13, 1995 PCT Pub. No. WO96/10694 PCT Pub. Date Apr. 11, 1996The nozzle plate according to the present invention includes an axial passage for a fluid, particularly for a fuel, which is made up in the downstream direction by a filter, a ring chamber and an uninterrupted ring gap following one another. Using this arrangement, a cohesive tulip-shaped jet lamella can be produced which thins out in the downstream direction and then disintegrates into tiny droplets. As a consequence, the exhaust emission of an internal combustion engine can be further reduced and likewise a reduction of the fuel consumption can be achieved. The nozzle plate is suited particularly for injection valves in fuel injection systems of internal combustion engines with externally supplied ignition which compress the mixture.
