Regulator For Gas Fuel
Abstract: A regulator for a gas fuel is assembled so that assembling properties are not impaired, but any abnormal noise is not generated from a connecting portion between a valve shaft and a diaphragm. A regulator 1A for a gas fuel includes a pressure regulation valve constituted of a valve body 11 formed at a middle position of a valve shaft 10 and a sheet member 16, and a shaft head 12 formed by enlarging a diameter of a tip side of the valve shaft 10 is inserted into and engaged with a shaft head inserting portion 21 formed on the center lower portion side of a diaphragm 14. The regulator for the gas fuel decreases and regulates, to a predetermined pressure, a pressure of the gas fuel introduced while opening and closing the pressure regulation valve by a displacement operation of the diaphragm 14, to forward the gas fiiel to a downstream side. In the regulator 1A for the gas fuel, in a cormecting portion between the shaft head 12 and the shaft head inserting portion 21, a gap filling member 23 made of a resin to prevent the shaft head 12 from moving in an axial direction in a gap formed between the upper surface of the shaft head 12 and a top wall of the shaft head inserting portion 21 is disposed in the shaft head inserting portion 21 so as to fill in the gap between the shaft head 12 and the shaft head inserting portion, thereby avoiding the continuous collision of the outer surface of the shaft head 12 vvith the inner surface of the shaft head inserting portion 21 due to the vibration of the diaphragm 14.
