PROBLEM TO BE SOLVED: To compactly attach various kinds of valves and a water hammer preventer in a narrow space by combining both. SOLUTION: A buffer chamber 4 is formed of a main body 1 and a lid member 2. A valve unit 7 is slidably arranged via coil springs 8, 9 in the chamber 4. A high-speed fluid flow flowing in from an inlet 5 or an outlet 6 is buffered by compressing the coil spring 9 or 8 with the valve unit 7, to prevent water hammer from occurring. |
