Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/199742
Kind Code:
A1
Abstract:
This valve device is provided with: a first outer layer (Y11); a second outer layer (Y13); and an interlayer (Y12) forming a fluid chamber (Y19). A first flow hole (Y16) enabling communication with the fluid chamber is formed in either the first outer layer or the second outer layer. A second flow hole (Y17, Y171-Y175) enabling communication with the fluid chamber is formed in either the first outer layer or the second outer layer. The interlayer includes: drive parts (Y123, Y124, Y125) that are displaced when their own temperature changes depending on whether there is electrical conduction; a displacement amplification member (Y131) that is urged by the drive parts and also amplifies the displacement of the drive parts when the drive parts are displaced; a movable part (Y127) that receives at a force point (YV1) the displacement that has been amplified by the displacement amplification member and thereby rotates about a fulcrum (Y126); and a valve element (Y128) for adjusting the degree of opening of the second flow hole with respect to the fluid chamber, by being urged from an application point (YV3) of the movable part and moving within the fluid chamber when the movable part rotates.
