Transmission elements of an adjustment gear mesh on the arms of the double-armed lever. The transmission elements are rigid pushrods, and the levers have been configured in an articulated manner on the ends of the rotary flap shafts. The swivel axes of the levers are parallel to a line that intersects the rotation axes of the pushrods at the lever arms. Hubs have been rigidly connected to the ends of the rotary flap shafts. The hubs are supported with the aid of springs against the intermediate levers mounted on the ends of the rotary flap shafts.
