ABSTRACT:
An air inlet control device for a ventilating, heating and/or air conditioning system in a motor vehicle comprises a main valve pivotable about a first axis of rotation for selectively closing off a recirculated air inlet and a fresh air inlet, and a pressure adjusting valve, which is also movable pivotally so as to act on the dynamic pressure of the air at the fresh air inlet when the main valve is covering the recirculated air inlet. The pressure adjusting valve has an axis of rotation which is carried by the main valve and which is spaced away from the axis of rotation of the main valve.
