<p>The regulator consists of a series of parallel vanes (2) connected to a supporting frame (3) so they can be opened or closed to control the flow passing between them. The vanes and frame are moulded in one piece from a synthetic material, such as polypropylene, with each vane connected to a bar (10) and to the frame (3) by thin bridges (4, 11) of the synthetic material. The frame is additionally equipped with assembly elements (12) for attaching it to a supporting structure in the vehicle.</p> |
