Document Type and Number:
WIPO Patent Application WO/2022/239524
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide a coupling system that can reliably cause a fluid to flow between a flow passage of a male member and an exterior section of a female member, while also reducing or preventing crushing or damage of a receiving section due to the male member. The present invention comprises a male member 1 that has a flow passage 10 through which a fluid flows, a female member 2 that has a guidance passage 20 into which the male member 1 is inserted, and a check valve 3 that is provided to an aperture section 20b of the guidance passage 20 of the female member 2. The check valve 3 comprises a stopper section 31 that blocks or opens the aperture section 20b of the female member 2, a membranous elastic body 32 that is integrally provided at the periphery of the stopper section and has a passage hole 32a through which the fluid passes. An attachment section 33 that is integrally provided at the periphery of the membranous elastic body 32 and is attached to the female member 2. The stopper section 31 is integrally provided with a receiving section 34 for receiving the male member 1, and a plurality of linear flow sections 34a for the fluid to flow through are formed in the receiving section 34.
