Title:
AIR-TIGHT DEVICE FOR VEHICLE DOOR
Document Type and Number:
Japanese Patent JP3323938
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suck air in an exhaust pipe by Venturi action of a restriction part by connecting an exhaust pipe of a seal material to a control compressed air supply pipe, and forming a throttling pipe on the upstream side of a connecting part between the control compressed air supply pipe and the exhaust pipe.
SOLUTION: A seal material 1 for forming an air-tight device is formed to be hollow in section in such a manner as to be expanded and contracted, and disposed in the periphery of an entrance for a vehicle. A compressed air supply and distributing pipe 2 is connected to the seal material 1, and when a door is closed, the seal material 1 is expanded by compressed air supplied from a supply pipe 4 to closely adhere to the outer peripheral part of the door, so that air-tightness in the entrance part of the vehicle is kept. On the other hand, when the door is opened, a solenoid three-way valve 3 is switched to the exhaust side. Thus, air in the exhaust pipe 5 is sucked by the Venturi action when compressed air flowing through a control compressed air supply pipe 6 passes through a restriction part 7, whereby the compressed air in the seal material 1 can be exhausted in a short time.
