Claims

[Claims for Utility Model Registration] (1) An elastic orifice whose duct cross-sectional area is deflected by changes in the flow rate of fluid is provided with a check valve operated by a spring that resists the flow on the fluid outlet side of the orifice. , a check valve with flow rate control configured to close the orifice pipeline when the fluid is stationary; (2) A check valve with flow rate control having the structure according to claim 1 of the utility model registration claim, in which the check valve with flow rate control is integrally formed in the water supply port of the water supply valve. (3) A check valve with flow rate control having the structure as set forth in claim 1 of the utility model registration claim, in which the outer periphery of the bottom surface of the orifice is formed into a flange shape as a sealing part.
