Claims

[Scope of utility model registration request]

Pressure adjustment in which a spring force and fluid pressure in a fluid system are applied to a pressure detection member in opposition, and when an imbalance occurs in these, the pressure detection member moves to drive the main valve body to open or close. In the valve, an adjustment chamber that absorbs a change in volume of the operating pressure chamber is provided in a pressure detection passage that communicates the fluid system with an operating pressure chamber that applies fluid pressure to one surface of the pressure detection member; A pressure regulating valve, wherein the regulating chamber is provided with a restriction that restricts movement of fluid between the operating pressure chamber and the fluid system.
