  • Active pressure relief valve for automatic air extractor
    Patent number: 9889723
    Abstract: 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.
