Abstract

Kraftstoff-Einspritzdüse für Brennkraftmaschinen, mit einer Ventilnadel (22) und einer Schließfeder (24), die sich über einen scheibenförmigen Meßwertgeber (40) an einer gehäuse­ festen Schulter (42) abstützt. Der Meßwertgeber (40) hat als druckempfindliches Bauelement einen niederohmigen Wider­ standskörper (44), vorzugsweise einen Dickschichtwider­ stand, dessen Widerstandsänderungen in einer Brückenschal­ tung verarbeitet werden. Ein solcher Widerstandskörper läßt sich einfach kontaktieren und isolieren und liefert Signale, die unabhängig von der Änderungsgeschwindigkeit der Schließ­ federkraft sind.
