AIR EXTRACTOR SYSTEM TO MITIGATE VACUUM-EFFECT IN A PASSENGER COMPARTMENT OF A MOTOR VEHICLE
First Claim
Patent Images
1. An air extraction system for a motor vehicle, comprising:
- an air extractor including an air flow control valve;
an actuator operatively connected to said air flow control valve; and
a controller configured to activate said actuator and open said air flow control valve when a closure of said motor vehicle is opened thereby mitigating a vacuum-effect otherwise created in a passenger cabin of said motor vehicle.

Abstract
An air extraction system is provided for a motor vehicle. That air extraction system includes an air extractor having an air flow control valve and an actuator operatively connected to the air flow control valve. Further the system includes a controller configured to activate the actuator and open the air flow control valve when a closure of the motor vehicle is opened thereby mitigating a vacuum-effect otherwise created in the passenger cabin of the motor vehicle. Such a system is particularly effective in mitigating moon roof draw down on moon roof equipped motor vehicles. A related method is also provided.

12. An air extractor system for a motor vehicle, comprising:
-
an air extractor including an air flow control valve; a controller; and an actuator responsive to said controller to open said air flow control valve whereby said air flow control valve opens passively to release positive air pressure from a passenger compartment of said motor vehicle and opens actively by means of said actuator to mitigate negative air pressure in said passenger compartment of said motor vehicle.
