Abstract
The present invention relates to an apparatus for controlling the supply of intake air to a vehicle, incorporating a control unit which is arranged to indicate and initiate supply of intake air to at least three intake air regions in the vehicle which usually comprise a defroster region, a panel region and a floor region. The apparatus incorporates a control arrangement which is designed, depending on the setting of the control unit, to control dampers (15 A-C) which are situated in ducts which lead to the intake air regions. The control arrangement incorporates a cam arrangement designed to act upon an arm (14 A-C), arranged for each inlet air region, for variable setting of at least one of the dampers (15 A-C) between an open and a closed position. The cam arrangement incorporates at least two movable cam devices (11) which each incorporate an external cam surface (13) with a cam height which varies along the cam surface, and each of the arms (14 A-C) is designed, by means of a contact device (16 A-C), to bear upon and be acted upon by whichever of the cam surfaces (13) of the two cam devices (11) exhibits the larger cam height in the region of the contact device (16 A-C).
