<p>Device for the adjustment of a ventilation grill, characterised in that it principally consists of two feelers (14, 15) placed in the flow opening S of the ventilation grill of which the first feeler (14) measures the temperature of the airflow and transmits this value to a processing unit (16), and of which the second feeler (15) is brought up to and maintained at a temperature which is higher than the temperature of the first feeler (14) and whereby the power that is required in order to maintain the second feeler (15) at the higher temperature is also communicated to the processing unit (16) in order to regulate the power supply of the heating unit of the feeler (15); and on the movable part (4) that determines the flow opening S of the ventilation grill, driving means (13) for this movable part (4) of which the power supply is regulated by the aforementioned processing unit (16).</p> |
