摘要： The present invention provides a gas pressure regulating valve capable of, even under a high-pressure fuel gas circumstance, more precisely regulating secondary pressure of the high-pressure fuel gas to target pressure and preventing the fuel gas from leaking to the atmosphere.
An electromagnetic pressure regulating valve 1 includes a valve body 14 and causes a valve body 14 to move by an electromagnetic proportional solenoid 27 to adjust an opening degree of a valve passage 13, thereby regulating secondary pressure p 2 to target pressure. A pressure return chamber 24 is formed in the housing 12, and a diaphragm seal 19 is provided at the valve body 14. The diaphragm seal 19 receives the secondary pressure p 2 of the pressure return chamber 24 to cause the valve body 14 to move toward a closed position. A bearing member 18 is provided between the valve body 14 and the housing 12. In a gap between the valve body 14 and the housing 12, a high-pressure sealing member 20 is provided closer to the valve passage 13 than the bearing member 18, and a low-pressure sealing member 21 is provided closer to the bearing member 18 than the high-pressure sealing member 20. A buffer chamber 22 connected to a secondary port 12c is formed between the sealing members 20 and 21.
