ABSTRACT:
In a fuel injection valve, after a preliminary adjustment of the valve seat support and immobilization thereof on the valve housing by way of a flanged rim, the effective stroke of the valve needle is measured, with the magnet coil energized, using an electrical displacement measurement system, and compared in the electronic control device to the reference stroke. In the event of a difference between these two values, the electronic control device activates a welding device which generates in an adjusting segment a first circumferential weld bead whose shrinkage upon cooling results in a decrease in the effective stroke. If, in a new measurement and adjustment cycle, the effective stroke still differs from the reference stroke, further weld beads are generated. The fuel injection valve is suitable particularly for the injection of fuel directly into the combustion chambers of internal combustion engines.
