ABSTRACT:
In a liquid filling machine wherein a liquid is fed in a specified quantity at a time from a metering cylinder to a filling nozzle by the operation of a piston housed in the cylinder, a device for preventing the liquid from dripping from the filling nozzle comprises a check valve disposed in the nozzle and movable upward or downward by a change in the internal pressure of the metering cylinder produced by the operation of the piston. The upward movement of the valve produces a negative pressure within the nozzle to prevent the liquid from dripping from the nozzle. The negative pressure is variable in accordance with the properties of the liquid by adjusting the stroke length of upward or downward movement of the check valve.
