としたことを特徴とする圧力調整弁。[Claims for Utility Model Registration] A stem interposed between a valve body and a diaphragm assembly that are biased in the valve closing direction by a closing spring, and a stem that is biased in the valve opening direction via the diaphragm assembly and stem. In the pressure regulating valve, the pressure regulating spring is provided with a diaphragm that is provided with a siphon tube that communicates between the diaphragm chamber, which applies air pressure on the secondary side in a direction that opposes the pressure regulating spring, and the output port side. A piston is provided on the stem of the piston, and the cylinder portion that accommodates the piston is placed in a position that communicates with the outlet side so that secondary pressure acts on one side of the piston, and the cylinder portion that accommodates the piston is placed in a position that communicates with the outlet side. A pressure regulating valve characterized in that the two are communicated through a communication hole with a raised side on the cylinder side, so that primary pressure acts on the cylinder.
