Abstract:
PROBLEM TO BE SOLVED: To regulate supply pressure of compressed air to an object to be filled with air without providing a relief valve, and improve relief accuracy.SOLUTION: A pressure gauge 6 includes a cylindrical trunk 18 communicating with a surge chamber 12B, a piston 19 capable of moving in the cylindrical trunk 18 in a lengthwise direction with compressed air, and a spring 20 configured to energize the piston 19 to a front end side. The cylindrical trunk 18 comprises a small-diameter trunk 18F sealed by a seal ring 25 of the piston 19, and a large-diameter trunk 18R continuing to the small-diameter trunk through a stage part K and capable of forming an interval D between itself and the seal ring 25. When the compressed air reaches specified pressure and the seal ring 25 goes over the stage part K, the compressed air is discharged from the interval D.SELECTED DRAWING: Figure 4
