<p>The fresh air supply system for a vehicle has a distribution duct (1) under the windscreen (3) and provides controlled airflows to the windscreen, the feet of the occupants and to facial jets (6). The distribution duct is fitted as one replacement unit and has a common inlet port (1'). The windscreen defrost jets (2) are coupled to a common control with the foot jets (5) while the facial jets are controlled independently. The common control has three ranges with one range for either set of jets to be controlled independently. A middle range acts as a distribution range with progressive increase of one airflow balanced by progressive increase of the other.</p> |
