PROBLEM TO BE SOLVED: To provide a filling nozzle for a liquid filling apparatus which has a simple and inexpensive configuration and prevents liquid drip.SOLUTION: A filling nozzle includes: a suction valve; a filling piston connected to a filling cylinder; a discharge valve, a leading-end mesh, and a filling nozzle body having a suction chamber and a filling chamber. The suction valve is a valve for sucking a filled liquid from a filled liquid tank into a filling nozzle body by moving a filling piston in a sucking direction. After the filled liquid is sucked into the filling nozzle body, the filling piston moves in a discharging direction opposite to the sucking direction, thereby opening the discharge valve such that the filled liquid is moved to the filling chamber. Consequently, the filled liquid is discharged from a discharge port provided with a leading-end mesh and is injected into a container. Additionally, the discharge valve includes: a first spring supporting a shaft provided through the top and bottom of the discharge valve; and a second spring supporting the discharge valve. The filling nozzle prevents liquid drip from the leading-end mesh. |
