Claims

[Claims for Utility Model Registration] A rod-shaped valve body having a valve portion at the tip and supported movably in the axial direction is provided in the gas chamber on the inlet side communicating with the gas inlet, and is compatible with the above-mentioned valve body. In a gas flow regulator equipped with a fixed member that has a valve seat on the end face and a flow path in the direction of the valve seat that communicates with the gas outlet, if the valve part of the valve body is made of a bare rod, it will be difficult to fix it. A minimum flow hole passing through the side wall of the member is provided, a flow path toward the valve seat is communicated with the inlet side gas chamber through the minimum flow hole and the outer peripheral surface of the valve seat, and the valve portion is connected to a large diameter valve portion. A gas flow regulator characterized in that the valve part has a two-stage shape, and the large-diameter valve part has a small-diameter valve part provided on an end surface of a pedestal projecting from the large-diameter valve part.
