Abstract
A fuel injection nozzle for internal combustion engines is proposed, having a valve needle and an induction coil, the armature of which is coupled with the valve needle and which serves to emit signals depending on the needle stroke or needle speed for a measuring device which can be connected to the injection nozzle. The induction coil is associated with a coil core, which is disposed such that it is displaceable in the axial direction in such a manner that a predetermined value for the initial inductance of the induction coil can be adjusted independently of the tolerances of the individual structural parts of the injection nozzle.
