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

    【課題】 被空気充填物への圧縮空気の供給圧力を、リリーフバルブを設けることなく規制しうるとともに、リリーフ精度を向上させる。【解決手段】 圧力計6は、前記サージ室12Bに通じる筒状胴部18と、圧縮空気により筒状胴部18内を長さ方向に移動しうるピストン19と、ピストン19を前端側に付勢するスプリング20とを具える。筒状胴部18は、ピストン19のシールリング25にシールされる小径胴部18Fと、それに段差部Kを介して連なりシールリング25との間に隙間Dを形成しうる大径胴部18Rとからなる。圧縮空気が規定圧力に達し、シールリング25が段差部Kを越えたとき、圧縮空気を隙間Dから排出する。【選択図】図4
