Apparatus for filling specified amount of liquid
 An apparatus for filling a specified amount of liquid comprises a vertical tubular nozzle having a large-diameter portion intermediately of its height and a valve seat at the edge of an open lower end thereof, a valve upwardly and downwardly movably supported by the filling nozzle and comprising a plug intimately fittable to the valve seat and a stem extending upward from the plug inside the nozzle, a resistance member fixed to the valve stem so as to be positioned in the large-diameter portion for acting against a downward flow of liquid, a spring biasing the valve upward to hold the plug in intimate contact with the valve seat against the gravity on the liquid within the nozzle, a metering cylinder for intermittently feeding the liquid into the nozzle in the specified amount at a time so that the valve is opened by the pressure of flow of the liquid against the spring, and the spring closing the valve when the feed of liquid is discontinued. The large-diameter portion has a diameter gradually increasing as it extends from its upper end downward.
