Abstract

Bei derartigen Kunststoff-Drosselklappenstutzen werden Potentiometer beispielsweise mit Schrauben an den Stutzen angeschraubt.With such plastic throttle bodies, potentiometers are used for example screwed to the nozzle with screws.

Hiergegen weist der neue Stutzen die Merkmale auf, daß das Potentiometergehäuse im Drosselklappenstutzen (1) ausgebildet ist und dort einen Anschlußsteckerschacht (4) und eine Potentiometerkammer (5) aufweist.In contrast, the new nozzle has the features that the Potentiometer housing is formed in the throttle valve connector (1) and there one Has connector shaft (4) and a potentiometer chamber (5).

Hierdurch ist die Anzahl der Bauteile und Fertigungsschritte reduziert.
