PROBLEM TO BE SOLVED: To provide a pressure adjustment valve which allows its productivity to be increased and furthermore allows variations in its accuracy of pressure adjustment to be suppressed.SOLUTION: A valve seat member 42, a valve element 52, and a coil spring 51 are provided in the body 12 of a pressure adjustment valve 11. When the valve element 52 is away from the valve seat member 42, CNG (Compressed Natural Gas) in a valve chest 41 is flowed out to an outlet part 19 through the communication passage 523 of the valve element 52, and when the valve element 52 seats on the valve seat member 42 and the communication passage 523 is blocked by the valve seat member 42, the outflow of the CNG from inside of the valve chest 41 to the outlet part 19 is restricted. The pressure adjustment valve 11 also includes an adjustment screw 40 for supporting the valve seat member 42. The adjustment screw 40 can be displaced in an axial direction while maintaining a state where the valve chest 41 opening to outside is blocked. |
