Abstract

Die Erfindung bezieht sich auf eine Stelleinrichtung für eine Zumeßeinrichtung, insbesondere Drosselklappe (11) einer Brennkraftmaschine mit Leerlaufdrehzahlregelung, bei der die im Ansaugrohr (10) angeordnete Drosselklappe mit einem Ver­ stellgestänge (16) verbunden und durch eine Rückholfeder (14) vorge­ spannt ist und ein erster einstellbarer (28) und ein zweiter fester Anschlag (30) für einen Betätigunghebel (13) der Drosselklappe vorgesehen sind, wobei der zweite feste Anschlag den Ein­ stellbereich des ersten Anschlags für eine minimale Öffnung der Drosselklappe begrenzt. Ein vorzugsweise als einstücki­ ger Hebel (21) ausgebildeter Leerlaufanschlag wirkt mit den beide beaufschlagt. Durch Zusammenwirken des Leerlaufan­ schlaghebels mit den beiden Anschlägen (30,28) ist einerseits eine Regelung der Leerlaufstellung der Drosselklappe gewährlei­ stet, wobei eine minimale Öffnungsstellung festgelegt ist, und ferner ist eine Leerlaufstellung der Drosselklappe mit etwas größerer Öffnung als der minimalen Öffnung für den Fall sichergestellt, daß es zu einem Ausfall oder Defekt der Leerlaufdrehzahlregelung kommt. The invention relates to an actuating device for a metering device, in particular a throttle valve (11) Internal combustion engine with idle speed control, at the throttle valve arranged in the intake pipe (10) with a ver connecting rod (16) connected and pre-fed by a return spring (14) is tensioned and a first adjustable (28) and a second fixed stop (30) for an actuating lever (13) of the throttle valve are provided, the second fixed stop the one Adjustment range of the first stop for a minimal opening the throttle valve is limited. One preferably as one piece The lever (21) designed idle stop works with the both acted upon. By cooperating with idle the impact lever with the two stops (30, 28) is one Ensure control of the idle position of the throttle valve stead, whereby a minimum opening position is fixed, and also an idle position of the throttle valve with slightly larger opening than the minimum opening for the Case ensures that there is a failure or defect the idle speed control comes.
