ABSTRACT:
In order to control the air throughput through the intake pipe of an internal combustion engine, the power of which is controlled by displacement of a throttle valve, there is provided in the intake pipe in known manner a dome-shaped contour which follows the throttle valve over a part of the adjustment angle. Also, the cable pulley has a circular shape in a useful region of operation, but the pulley is fastened eccentrically on the throttle valve. In this way, there is obtained a sensitive displacement by electric motor of the throttle valve in the idling range on the one hand, and a very direct response of the throttle valve to a movement of the gas pedal on the other hand.
