Abstract
The present invention refers to a setting device for a feed device, particularly a throttle valve of an internal combustion engine with idling speed-of-rotation control in which the throttle valve, arranged in the intake pipe, is connected with a displacement rod and is pretensioned by a return spring. A first adjustable stop and a second fixed stop are provided for an actuating lever of the throttle valve, the second, fixed stop limiting the adjustment range of the first stop for a minimum opening of the throttle valve. An abutment member which is preferably developed as a lever cooperates with the two stops and is acted on by a mechanical reset means. By cooperation of the abutment member with the two stops, a control of the idling position of the throttle valve is one the one hand assured, a minimum opening position being fixed, and further an idling position of the throttle valve with a somewhat larger opening than the minimum opening is assured for the event that there should be a failure or a defect of the idling speed-of-rotation control.
