Title:

PRESSURE REDUCING VALVE

Document Type and Number:

WIPO Patent Application WO/2015/152338

Kind Code:

A1

Abstract:

Provided is a pressure reducing valve for reliably damping a vibration phenomenon that occurs in a pressure reducing member or a pressure receiving piston. When a pressure receiving piston (19) advances rightward and the capacity of a fluid chamber (28), which is formed to be partitioned by the pressure receiving piston (19) and a piston hole (18), increases, the pressure of the fluid chamber (28) decreases and a check valve (34) closes, and a pressurized fluid of an outlet chamber (10) flows into the fluid chamber (28) via a throttle portion (31). When the pressure receiving piston (19) retracts leftward and the capacity of the fluid chamber (28) decreases, the pressure of the fluid chamber (28) rises and the check valve (34) opens, and the pressurized fluid in the fluid chamber (28) flows out to the outlet chamber (10).
