Title:
WALL SURFACE SUCTION-TYPE TRAVEL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/135229
Kind Code:
A1
Abstract:
This wall surface suction-type travel device (10) is capable of travelling on a wall surface while applying suction to the wall surface. An intermediate chamber (24) communicates with a recessed decompression chamber (22A) which faces the wall surface. A suction device (30) sucks air from the intermediate chamber (24) to decompress the intermediate chamber (24). A main communication part allows the decompression chamber (22A) to communicate with the intermediate chamber (24). An auxiliary communication part allows the decompression chamber (22A) to communicate with the intermediate chamber (24). A valve body (28) is disposed facing an opening (18c) of the main communication part. The area of an opening of the auxiliary communication part is smaller than the area of the opening of the main communication part. When the pressure of the decompression chamber (22A) becomes higher than the pressure when suction is applied to the wall surface, the valve body (28) closes the opening (18c) of the main communication part as a result of the pressure difference between the decompression chamber (22A) and the intermediate chamber (24).
