Abstract

Bei einer Kraftstoffeinspritzpumpe für Brennkraftmaschinen mit einem Pumpenkolben (18), einer Antriebswelle (11) zur Betätigung des Pumpenkolbens (18) und einem Drehwinkelsensor (30) zur Erfassung der Drehwinkelstellung der Antriebswelle (11), dessen Impulsgeber als ein auf der Antriebswelle (11) drehfest sitzendes Geberrad (32) und dessen Impulsaufnehmer (31) an einem auf der Antriebswelle (11) drehbar sitzenden Trägerring (35) gehalten ist, ist zum Zwecke der eng tolerierten exakten Zuordnung von Impulsgeberrad (32) und Impulsaufnehmer (31) sowohl in radialer als auch in axialer Richtung der Impulsaufnehmer (31) in einem Sensorgehäuse (40) aufgenommen und dieses über Steckelemente form- und kraftschlüssig am Trägerring (35) festgelegt. Am Sensorgehäuse (40) sind Gleitflächen (41, 42), die auf gegenüberliegenden Stirnseiten des Impulsgeberrads (32) anliegen, und eine Anschlagfläche (46) ausgebildet, die in Radialrichtung mit einer Anschlagfläche am Trägerring (35) korrespondiert.
