Problems solved by technology

[0004] However, in the fluid controller of the aforementioned Patent Document 1, the addition of the anti-vibration spring has the same effect as changing the style of the pressure setting spring, so there is a problem of affecting the opening and closing of the diaphragm, that is, affecting the pressure control operation.

Abstract

Provided is a fluid controller of which the vibration-proof performance is improved without affecting its pressure control operation. A valve element (4) is moved relative to a valve seat (3) due to a change in balance between the fluid pressure applied to a diaphragm (10) and the elastic force by a pressure setting spring (13), whereby the fluid pressure is controlled. A vibration-proof member (17) is disposed on a disk-like movable member (12) moving integrally with the diaphragm (10). The vibration-proof member (17) has a weight interposed between elastic bodies built in a casing.

Description

technical field [0001] The present invention relates to a fluid controller called a pressure reducing valve, and more particularly to a fluid controller with improved vibration resistance. Background technique [0002] As a vibration suppressing mechanism for a fluid controller, Patent Document 1 discloses a fluid controller. A valve seat and a valve body are provided on the valve chamber side of a diaphragm that divides the interior of the fluid controller into a valve chamber and an adjustment chamber. A pressure setting spring is installed on the side of the adjustment chamber, and an anti-vibration spring that can change the overall spring constant and weight is interposed between the diaphragm and the pressure setting spring. [0003] Patent Document 1: Japanese Patent Publication No. 4-13586 ( figure 1 ) [0004] However, in the fluid controller of Patent Document 1, the increase of the anti-vibration spring has the same effect as changing the style of the pressure s...
