Document Type and Number:
WIPO Patent Application WO/2024/084677
Kind Code:
A1
Abstract:
[Problem] Conventional relief valves have the problem wherein resistance increases during valve opening and a valve opening operation is not stable; thus, a countermeasure therefor is required. [Solution] A relief valve 10 in the present embodiment has: a base part 11 that comprises a valve seat 11Z surrounding a valve hole 13; a valve body 35 that has an annular abutment part 35D which abuts the valve seat 11Z; a slide support mechanism 40K that includes a shaft fitting part 31 which supports the valve body 35 to be capable of linear movement in the axial direction of a shaft 40; and a sealing member 21 that is provided to one of the valve seat 11Z or the annular abutment part 35D, where the other thereof comes into contact with the sealing member 21 as a sealing contact part. In the slide support mechanism 40K, the shaft 40 is tilted relative to the shaft fitting part 31 and clearances C1, C2 are provided that allow for a state of partial abutment in which only part of the sealing contact part in the circumferential direction abuts the sealing member 21.
