Document Type and Number:
Japanese Patent JP3021108
Kind Code:
B2
Abstract:
PURPOSE: To prevent a chance in air pressure on a vehicle body surface from being transmitted to the inside of a cabin by moving movable members which can change the opening areas of an air intake port and an exhaust port or a projection amount from the vehicle body based on detected signals such as ventilation amount, and cabin pressure to control the ventilation amount and cabin pressure and so on.
CONSTITUTION: The outside air is taken into a cabin A through an air intake port, provided with a movable member 1a, and the air in the cabin A is discharged to the outside of the vehicle through an exhaust port provided with a movable member 1b. Moreover, ventilation amount and cabin pressure and so on are detected, the detected signals are sent to the controller 3 of control devices 2-5 to move the respective movable members 1a, 1b, and the opening areas of the air intake port and the exhaust port, or the protruding amount from the vehicle body are changed to control ventilation amount, cabin pressure and so on. It is thus possible to prevent a change in air pressure on the vehicle body surface from being transmitted to the inside of the cabin A.
