<p>The invention relates to a ventilating device for a motor vehicle interior. The device comprises a casing (10) provided with an external air inlet (16), with a recycled air inlet (18) and with an air outlet (50), a fan (38) housed in the casing, an adjusting flap (26) slaved to the speed of the vehicle to open or close the inlet (16) completely, a grid (30) with valves which are sensitive to the pressure difference, so that these valves open when the pressure of air on the casing side is less than the pressure of air on the interior side when the adjustment flap is in the completely closed position. The ventilation device of the invention makes it possible to stabilise the air flow rate flowing into the interior, this being regardless of the speed of the vehicle. <IMAGE></p> |
