AIR EXTRACTORS
First Claim
1. An air extractor assembly mounted in a body panel of an automotive vehicle, comprising:
- a first extractor valve having a first flap biased toward a closed position covering a first aperture defined within the body panel, the first flap opening when pressure within a cabin of the vehicle exceeds atmospheric pressure by more than a first predetermined pressure;
a second extractor valve having a second flap biased toward a closed position covering a second aperture defined within the body panel, the second flap opening when pressure within a cabin of the vehicle exceeds atmospheric pressure by more than a second predetermined pressure; and
a frame magnetic strip applied around the periphery of the second aperture.

Abstract
An air extractor assembly for an automotive vehicle is disclosed which has first and second air extractor valves mounted in a body panel. The first air extractor valve opens when pressure within the passenger compartment at a first pressure differential and the second air extractor valve opens at a second higher pressure differential. The second flap has a weight, which by virtue of gravity, resists opening. The weight can be a magnetic strip that is attracted to a ferrometallic and/or magnetic strip applied around the second aperture. By providing air extractor valves which open at different pressure differences, only the first air extractor valve opens when the pressure difference is in a lower range thereby limiting noise transmission into the passenger compartment. When a car door is shut and/or the climate control system is operating at maximum, the pressure difference is greater causing both extractor valves to open.
