Abstract:
1. An air valve arrangement for a motor vehicle, comprising: a frame comprising an air passage opening having a passage opening area; an air valve provided on said frame so as to be rotatable thereto about an axis in opposing directions of relative rotation, 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 shut-off position reducing the passage opening area of the air passage opening from in the passage position; and a drive, which is designed to drive the air valve in at least one first direction of the relative rotation about the axis; wherein the air valve is coupled to a preloading device, which preloads the air valve toward the passage position in a direction of relative rotation; wherein the preloading device comprises an at least two-part housing, with a first housing part non-rotatable relative to the frame and with a second housing part non-rotatable relative to the air valve; wherein a preloading means is accommodated in the interior of the housing; wherein the first and the second housing parts are coupled to one another in a torque-transmitting manner via the preloading means.
