項１記載の空気レギユレータ。[Scope of Claim for Utility Model Registration] (1) A primary pressure inlet; a secondary pressure outlet; a main valve that opens and closes between the primary pressure inlet and the secondary pressure outlet; and the secondary pressure outlet; A floating piston having an exhaust hole that moves according to the pressure difference in the pilot pressure chamber; when this floating piston moves toward the secondary pressure extraction chamber, it contacts the exhaust hole and closes it, and the pilot pressure chamber is closed. a relief valve provided integrally with the main valve, which opens the exhaust hole when moved to the side;
and a pressure regulating mechanism for controlling the introduction of pressure from the secondary pressure outlet into the pilot pressure chamber, wherein a diaphragm chamber is provided on the secondary pressure outlet side of the floating piston and between the floating piston and the air regulator. The invention is characterized in that a buffer is provided that defines a diaphragm chamber, a communication hole with a secondary pressure outlet is bored in the buffer, and a sealing means is provided to cut off communication between the diaphragm chamber and the exhaust hole. air regulator. (2) The air regulator according to claim 1, wherein the sealing means comprises an annular bellows whose lower end is connected to the buffer and whose upper end is connected to the floating piston inside the communication hole.
