Abstract
A fluid valve has a valve plug configured as follows. In order to control a flow rate of a fluid between a first pressure chamber and a second pressure chamber, the valve plug is provided so as to be openable and closable in accordance with a difference between forces generated by pressures in the pressure chambers and resilience of an elastic member. The fluid valve includes an opening motion promoting portion. The opening motion promoting portion promotes an increase in degree of opening of the valve plug after the valve plug has been opened.

A fluid valve, comprising:
- a valve plug provided so as to be openable and closable in accordance with a difference between forces generated by a pressure in a first pressure chamber and a pressure in a second pressure chamber and resilience of an elastic member, in order to control a flow rate of a fluid between the first pressure chamber and the second pressure chamber;
- and
- an opening motion promoting portion that promotes an increase in degree of opening of the valve plug after the valve plug has been opened.
An opening motion promoting device that promotes opening of a valve plug included in a fluid valve, the valve plug being provided so as to be openable and closable in accordance with a difference between forces generated by a pressure in a first pressure chamber and a pressure in a second pressure chamber and resilience of an elastic member, in order to control a flow rate of a fluid between the first pressure chamber and the second pressure chamber,
- wherein the opening motion promoting device promotes an increase in degree of opening of the valve plug after the valve plug has been opened.
