Abstract

An air valve arrangement for a motor vehicle, comprising a frame and an air valve provided on said frame so as to be rotatable thereto about an axis of relative movement (R) in opposing directions of relative rotation, the frame comprising an air passage opening, and the air valve is provided in such a way on the frame that it is rotatable between a shut-off position and a passage position, the air valve in the passage position reducing a passage opening area of the air passage opening less than in the shut-off position, and further comprising a drive, which is designed to drive the air valve in at least one first direction of relative rotation about the axis of relative movement (R) for relative rotation, characterized in that the air valve is coupled to a preloading device, which preloads the air valve in a direction of relative rotation.
