Claims

[Scope of utility model registration request]

A main body having an inlet, an outlet, and a flow path connecting these two ports, an on-off valve provided in the middle of the flow path, a focusing chamber formed behind the valve body of the on-off valve, and a focusing chamber provided in the middle of the flow path. The pressure chamber is always connected to the primary side of the flow path via a small flow path provided on the valve body, and is also connected to the secondary side of the flow path by providing a relief valve on the valve body. Preferably, the relief valve is a metering valve configured to open and close the on-off valve by operating based on the main function part, and a metering valve having an outer diameter slightly smaller than the inner diameter of the valve seat on the front surface of the valve body. A metering valve characterized by being provided with a cylindrical protrusion that fits into a valve seat just before closing the on-off valve.
