Abstract

Eine Kraftstoff-Einspritzdüse mit Nadelhubsensor besitzt einen Düsenkörper (1) und einen an diesen über eine Zwischen­ platte (4) anschließenden Düsenhalter (8). Zwischen einer Ringschulter (23) der Düsennadel (3) und der Zwischenplatte (4) ist ein Arbeitsluftspalt (1) vorgesehen. Eine Spule (16) ist von einer von dem ferromagnetischem Material der Zwi­ schenplatte (4) begrenzte Bohrung (5) der Zwischenplatte ra­ dial entfernt angeordnet, wobei der für den Magnetkreis der Spule (16) maßgebende Fluß über den zwischen der Spule (16) und der Bohrung (5) gelegenen Abschnitt (19) der Zwischenplat­ te (4) und über den Arbeitsluftspalt (1) verläuft. Has a fuel injector with a needle stroke sensor a nozzle body (1) and one on this via an intermediate plate (4) adjoining nozzle holder (8). Between one Ring shoulder (23) of the nozzle needle (3) and the intermediate plate (4) a working air gap (1) is provided. A coil (16) is from one of the ferromagnetic material of the Zwi plate (4) limited bore (5) of the intermediate plate ra dial arranged remotely, the for the magnetic circuit of the Coil (16) decisive flux over the between the coil (16) and the bore (5) located section (19) of the intermediate plate te (4) and over the working air gap (1).
