Abstract

A valve device for an internal combustion engine includes a multi-part housing. A drive unit generates a rotational moment. The drive unit is arranged in a motor chamber. A transmission unit is arranged in a transmission chamber. An eccentric is configured to be driven by the transmission unit. A valve rod is configured to be displaceable in translation. The valve rod extends into a valve rod displacement chamber. A coupling element converts a displacement of the eccentric into a translational displacement of the valve rod. A valve seat is arranged between an inlet and an outlet. A valve closing body is attached to the valve rod. The valve closing body is configured to be lowered onto the valve seat and lifted off the valve seat. A cover is disposed between the eccentric and the coupling element. The cover is configured to separate the transmission chamber from the valve rod displacement chamber.
