Beschreibung
Zusammenfassung:	To positively retain a signal transducer coil within an insert ring, axially stacked on a fuel injection nozzle assembly, in which the induction coil provides an output signal upon axial reciprocating movement of the valve needle element of the injection valve, the opening is made large enough to receive a holding sleeve with an inwardly extending flange, the holding sleeve fitting over the induction coil and pressing the coil against the bottom wall of the opening. The holding sleeve, itself, preferably made of magnetic metal, is adhesively secured in the opening which, preferably, has a non-cylindrical shape, either extending conically or formed with a ring groove of, preferably, sawtooth cross section.
