Claims

[Scope of Claim for Utility Model Registration] (1) A hot water mixing faucet in which a pair of leg pipes are provided in a V-shape with the legs opened downward, and a water hammer shock absorber is provided on the leg pipes, as described above. As a water hammer shock absorber, there is a bench lily pipe having an inlet and an outlet for water supply, a communication port bored in the constriction part of the bench lily pipe that communicates the inside and outside of the bench lily pipe, and the inside divided into two chambers by a piston. a cylinder having one chamber communicated with the communication port; a spring provided in the other chamber within the cylinder to bias the piston toward the one chamber; and a spring communicating the other chamber with the atmosphere. 1. A hot water mixing faucet, characterized in that a water hammer shock absorber having an atmosphere communication port is installed such that the atmosphere communication port is located below the piston retraction limit. (2) In paragraph 1 of the claims for utility model registration,
The water hammer shock absorber further includes a check valve disposed between the other chamber and the atmosphere communication port to prevent air from flowing from the other chamber toward the atmosphere communication port. A hot water mixing faucet characterized by a buffer device.
