Document Type and Number:
WIPO Patent Application WO/2019/187867
Kind Code:
A1
Abstract:
A gasket 2 used to connect flow passage holes 13, 14 which are formed respectively in two piping blocks 11, 12 has formed on both the axial sides thereof a pair of cylindrical radially outside press-fit sections 23 which are press-fitted respectively into cylindrical radially outside sealing grooves 4 formed in end surfaces 11a, 12a of both the piping blocks 11, 12 at positions radially outside the flow passage holes 13, 14. The outer circumferential surfaces of the radially outside press-fit sections 23 have formed thereon sealing circumferential surfaces 232a which are in close contact with the outer circumferential surfaces 42 of the radially outside sealing grooves 4 to exhibit a sealing function. A groove 5 is formed in the outer circumferential surface of the gasket 2 such that, when one of the pair of radially outside press-fit sections 23 is press-fitted in sealing grooves 3, 4 in the piping block, the groove 5 is open on the outside axially of the end surface of the piping block.
