Japanese Patent JP5445343

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To achieve both securement of sealing performance and reduction of pressure loss in a fluid valve used at pressure below atmospheric pressure.SOLUTION: The fluid valve includes a partition member 51 in which a communication port 52 is formed, a valve body which is made from a thin plate elastic member and can block the communication port 52 by covering the communication port 52, and a support member 57 arranged in the communication port 52 and supporting the valve body by coming in contact with the surface of the valve body when the valve body blocks the communication port 52 block. A seal section 56 for sealing between the partition member 51 and the valve body when the valve body blocks the communication port 52 is arranged on a surface of the partition member 51 at a side where the valve body is arranged so as to surround an outer periphery of the communication port 52, and a peripheral-direction support member 571 with a shape along the seal section 56 is arranged as a support member 57. The peripheral-direction support member 571 is arranged at a side closer to an outer peripheral section of the communication port 52 rather than the center of the communication port 52 when viewed from a flow direction of a fluid circulating the communication port 52.
