ABSTRACT:
An air inlet for a heating or air-conditioning system is provided which includes a movable ram air flap for controlling inlet air flow as a function of relative vehicle speed and outside air speed and a circulating-air flap for controlling relative supply of fresh and recirculating air. The ram air flap and circulating air flap are arranged coaxially with respect to one another, supported in a common bearing in an intake housing. The air flaps are nested one radially inside the other, with the ram air flap having a smaller pivoting radius.
