A passenger vehicle comprises a passenger compartment with an interior space. An HVAC system conditions fresh air from outside the vehicle, wherein the HVAC system includes a main blower for delivering conditioned air to the interior space. An air extractor valve is fluidically coupled between the interior space and the outside, wherein the air extractor valve opens in response to a higher pressure in the interior space than an outside pressure. The air extractor valve substantially blocks air flow from the outside to the interior space. A supplemental blower is integrated with the air extractor valve for directing an exhaust flow from the interior to the outside, wherein the supplemental blower is activated as a function of the main blower. Alternatively, the supplemental blower is activated in response to a door being opened, enhancing the ability of the extractor to reduce door closing effort.

An air extractor assembly for an automotive vehicle includes a diaphragm seat attached to a panel of the vehicle's interior, a diaphragm movable between a closed position and an open position with respect to the diaphragm seat, and a position controller that regulates movement of the diaphragm. The position controller may be any one of a variety of linear movers and may be selected from the group consisting of a solenoid, a motor, a vacuum, and a plunger. The diaphragm includes a resilient member so that when the diaphragm is in its closed position, a tight seal is formed between the diaphragm seat and the diaphragm. The position controller is by any one of a variety of several regulating mechanisms operating alone or in combination. The regulating mechanism may include but is not limited to the vehicle HVAC system, an oxygen sensor, door latches, and a humidity sensor.
