Title:
減圧弁
Document Type and Number:
Japanese Patent JP6397651
Kind Code:
B2
Abstract:
There is provided a pressure reducing valve in which phenomena of vibration occurring with respect to a pressure reducing member and/or a pressure receiving piston are reliably dampened. When a pressure receiving piston (19) is advanced rightward to increase the volume of a fluid chamber (28) defined by the pressure receiving piston (19) and a piston hole (18), the pressure in the fluid chamber (28) drops to close a check valve (34), and the pressurized fluid in an outlet chamber (10) flows into the fluid chamber (28) through a throttle portion (31). When the pressure receiving piston (19) is retracted leftward to reduce the volume of the fluid chamber (28), the pressure in the fluid chamber (28) rises to open the check valve (34), and the pressurized fluid in the fluid chamber (28) flows out to the outlet chamber (10).
