Abstract
A setting device is provided for a feed device, in particular the throttle valve of an internal combustion engine with idling speed control, in which the throttle valve is located in the intake manifold. The throttle valve is connected to a displacement rod and 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 limits the adjustment range of the first stop for a minimal opening of the throttle valve. An idle stop, which is preferably developed as single-piece lever, acts with the actuating lever. By cooperation of the idle stop lever with the two stops, there is assured, on the one hand, a control of the idle position of the throttle valve, in which case a minimal opening position is established, while, on the other hand, an idle position of the throttle valve with a somewhat larger opening than the minimal opening is assured in the event that the idle speed control fails or becomes defective.
