An automotive air-conditioner has a motor-driven centrifugal fan and a casing accommodating the fan and having first and second wall portions adjacent to axially opposite open ends of the fan, respectively. A fresh-air inlet and a first recirculated-air inlet are formed in the first wall portion, while a second recirculated-air inlet is formed in the second wall portion to increase flow of recirculated-air sucked into the fan during a recirculation mode of air-conditioner operation. The fresh-air inlet and the first recirculated-air inlet are selectively opened and closed by a servo-actuated damper, while the second recirculated-air inlet is closed and opened by another servo-actuated damper operatively linked to the first-mentioned damper.

An automotive air-conditioner having a fan section and an air-conditioning section connected to a discharge side of said fan section to receive air therefrom and condition the thus received air, said air-conditioning section having at least one outlet through which the thus conditioned air flows into an occupant compartment, said fan section comprising: a centrifugal fan having a plurality of circumferentially arranged vanes and axially opposite open ends through which flow of air enter the fan; a fan casing accomodating said centrifugal fan; said fan casing having a first wall portion including a first suction port closely adjacent to one of the open ends of said fan, a second wall portion including a second suction port closely adjacent to the other open end of said fan, a first air induction portion connected to said first wall portion and defining a fresh-air inlet and a first recirculated-air inlet both adapted to be communicated with said one open end of said fan, and a second air induction portion connected to said second wall portion and defining a second recirculated-air inlet adapted to be communicated with the other open end of said fans; a first valve means for selectively opening and closing said fresh-air inlet and said first recirculated-air inlet; a second valve means for opening and closing said second recirculated-air inlet; and actuating means operatively associated with said first and second valve means to actuate them so that said fresh-air inlet and said first and second recirculated-air inlets are operated and closed by said valve means, said actuating means comprising a servomotor and a mechanical link mechanism drivingly connected said servomotor to said first and second valve means, said first and second valve means and said link mechanism being arranged such that, when said fresh-air inlet is opened by said first valve means, said first recirculated-air inlet is closed by said first valve means and said second recirculated-air inlet is closed by said second valve means and such that, when said fresh-air inlet is closed by said first valve means, said first recirculated-air inlet is opened by said first valve means and said second recirculated-air inlet is opened by said second valve means.
