<p>PROBLEM TO BE SOLVED: To provide a valve in which a valve element can endure high back pressure even when rigidity of the valve element is lowered.SOLUTION: A valve includes a valve disc 1 defining one chamber and the other chamber, a passage 11 formed on the valve disc 1 for communicating one chamber and the other chamber, an annular plate-shaped valve element 3 stacked on the valve disc 1 and opening and closing the passage 11, an annular first spacer 30 stacked at an anti-valve disc side of the valve element 3 and having an outer diameter smaller than an outer diameter of the valve element 3, a plate 31 disposed on an outer periphery of the first spacer 30, and a second spacer 32 stacked at an anti-valve disc side of the first spacer 30 and having an outer diameter larger than an inner diameter of the plate 31. The plate 31 is thinner than the first spacer 30, and axially movable along the first spacer 30.</p> |
