Abstract: The invention relates to an exhaust gas recirculation device for an internal combustion engine, especially for a motor vehicle, comprising an exhaust gas recirculation line for recirculating exhaust gas, the line branching off from the exhaust line and running into an unburned gas line. The exhaust gas recirculation line includes a valve having a closing element which can be displaced between a closing position and an opening position by means of an actuator. One aim of the invention is to especially reliably prevent the closing element of the valve from sticking to the valve seat after the operation of the internal combustion engine. To this end, the closing element of the valve is placed in an idle position by means of the actuator, when the internal combustion engine is not in operation.

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.
