Document Type and Number:
WIPO Patent Application WO/2014/142110
Kind Code:
A1
Abstract:
Provided is a valve device which is configured so that the valve device is capable of being manufactured at reduced cost by improving the sealing performance without providing an additional seal member.
A valve device is provided with: a housing (10) which has a fluid passage formed therein and which has an annular valve seat (13) formed at a position between the ends of the fluid passage; an adjustment valve (100) which closes the fluid passage by coming into contact with the valve seat (13), thereby being capable of disabling fluid from flowing through the fluid passage; and a drive mechanism which drives the adjustment valve (100). The adjustment valve (100) is elastically deformable and is provided with: a valve head section (120) which is capable of coming into contact with the valve seat (13); and a shaft section (110) which is configured as a separate body from the valve head section (120) and which connects the valve head section (120) and the drive mechanism (40).
