Title:
FLUID CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2022/071092
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fluid control valve which exhibits extremely high responsiveness not only when the pressure of a working fluid which has flown into a first flow path is high but also when the pressure of the working fluid in the first flow pat is low. A fluid control valve V is provided with a valve seat 45a, a valve body 61 that is brought into contact with and is separated from the valve seat 45a, a first biasing means 64 for biasing the valve body 61 in a valve closing direction, and a second biasing means 65 having a spring force smaller than that of the first biasing means 64. The fluid control valve V can discharge a working fluid through a second flow path 13 in accordance with the pressure of the working fluid in a first flow path 11. In the valve body 61, a base 62 biased by the first biasing means 64 and an opening/closing part 63 that is brought into contact with and is separated from the valve seat 45a are arranged so as to be divided in an axial direction. The second biasing means 65 is disposed so as to be able to separate the base 62 and the opening/closing part 63 from each other in the axial direction.
