Method and apparatus for eliminating sudden changes of pressure inside vehicles, in particular ground vehicles |
摘要 |
The invention relates to a device for eliminating sudden changes of pressure in a ventilated or air-conditioned vehicle, the device comprising: a detector for detecting changes in the pressure outside the vehicle and delivering signals representative of said changes; closure means for closing an outside air suction duct and an inside air rejection duct; a control unit receiving the signals from the detector and controlling closure of the ducts above a first determined rate of change in outside pressure, said unit also controlling re-opening of the ducts after said change in outside pressure has fallen below a second determined rate; and means for balancing the inside pressure and the outside pressure by a controlled flow of air between the outside and the inside of the vehicle, said means constraining the pressure inside the vehicle to change as a function of time at less than a set rate.
