ABSTRACT:
An apparatus for filling a specified amount of liquid comprising a metering cylinder having a piston therein, a vertical filling nozzle having an opening at its lower end and forcibly chargeable with a liquid from the metering cylinder by the operation of the piston, a damper for opening and closing the opening of the filling nozzle, a spring biasing the damper so as to hold the damper closed against the gravity acting on the liquid filling the nozzle while the damper is closed with the charging discontinued although permitting the damper to be opened with the pressure of the liquid forcibly charged into the filling nozzle from the metering cylinder, and a closing device adapted to act on the damper in its open state to close the damper when the charging of the liquid is discontinued and adapted to be brought out of action transmitting relation with the damper so as to permit the spring only to hold the damper closed before the charging of the liquid is subsequently started. The closing device includes bumper for mitigating the impact acting on the damper and a damper operating member when the damper is closed.
