PURPOSE: To provide a device for suppressing or limiting rapid pressure change of a vehicle, especially, a ground vehicle. CONSTITUTION: This is a device for suppressing rapid pressure change in a traveling vehicle set in ducts 10 and 11 for connecting the inside part of the vehicle with the outside part. This device is provided with at least one closing element 14 and 15 with air flow passages 23 and 24 left and at least one partition wall 16 deformable according to the action of an air pressure. When the pressure inside and outside the vehicle is rapidly changed, the partition wall 16 is pressurized to the passages of the closing elements 14 and 15 so that the passages 23 and 24 can be completely or partially closed. This device is applied to a rail vehicle. |
