Abstract
An apparatus for filling a specified amount of liquid comprising a metering cylinder having a piston therein, a vertical filling nozzle having an open lower end and feedable with a liquid from the metering cylinder by the operation of the piston, a damper for opening and closing the open lower end of the filling nozzle, a spring biasing the damper to hold the nozzle end closed with the damper while the feed of the liquid is discontinued, and an opening portion adapted to open the damper against the spring simultaneously with or immediately before the start of feed of the liquid with the damper closed and to be subsequently brought out of operative relation with the damper before the feed of the liquid is discontinued so as to render the damper closable by the spring.
