ABSTRACT:
A load adjustment device has a throttle valve 9 which determines the output power of an internal combustion engine and is connected, fixed for rotation, with a throttle-valve shaft mounted in a throttle-valve housing. A control element 8a cooperates with a driver 4 coupled to an accelerator pedal 1, and acts on the throttle-valve shaft. A setting path of the driver 4 is limited by a stop (LL.sub.max). Upon a resting of the driver 4 against the idle stop (LL.sub.max), the control element 8a is moveable by means of the electric motor 14 in the idle control range relative to the driver 4. The control element 8a can be brought via a coupling member against a moveable stop 75 so that the setting lever 71, together with the throttle valve 9, is displaceable only via the electric motor 14 into a minimum idle position.
