Gas fuel supply regulator

A gas fuel supply regulator comprising:

• a valve being provided in a fuel inlet to a pressure regulation chamber comparted by a diaphragm from a side of a back pressure chamber that communicates with an atmosphere side;
• and
• a valve lever including a base end that is firmly fixed to a valve body by a pin arranged on a side of a valve seat of the valve, a rear surface at a leading end of which is supported by a control pressure set spring provided according to atmospheric pressure on the side of the back pressure chamber, and a surface having a rod holding recessed part slidably arranged thereon and that holds a rod protruded to a side of the pressure regulation chamber of the diaphragm,
• wherein the valve body is opened by fuel of before pressure reduction which fuel is introduced from the fuel inlet to the pressure regulation chamber through the valve, the valve lever is slid, the diaphragm is operated through a coupling mechanism between the rod holding recessed part of the valve lever and the rod of the diaphragm, and pressure of the fuel in the pressure regulation chamber is reduced, and
• wherein a cross section of the rod holding recessed part of the valve lever is V-shaped.
