摘要： 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.

摘要： An apparatus for filling a specified amount of liquid comprises a vertical tubular filling nozzle, a damper attached to the lower end of the filling nozzle and pivotally movable upward and downward, a vertical rod supported upwardly and downwardly movably inside the filling nozzle, a connecting member connecting the free end of the damper to the lower end of the vertical rod, a spring biasing the vertical rod upward to hold the damper closed against the gravity on the liquid within the nozzle, and a metering cylinder for feeding the liquid to the nozzle in the specified amount at a time to open the damper against the spring. An annular seat facing downward is formed on the inner surface of the nozzle approximately at the midportion of its height. A liquid channel blocking annular member is mounted on the vertical rod so as to come into contact with the seat simultaneously when or immediately before the damper is closed. The volume of liquid fed from the metering cylinder to the nozzle at a time is greater than the volume of liquid to be accommodated in the nozzle in the portion thereof under the blocking member.

摘要： 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.
摘要翻译：一种用于填充特定量的液体的装置，包括其中具有活塞的计量筒，垂直填充喷嘴，其下端具有开口，并且通过活塞的操作被强制地从计量筒中充入液体;阻尼器，用于打开并且关闭填充喷嘴的开口，弹簧偏置阻尼器，以便在阻尼器关闭的同时充电中断的同时使阻尼器能够以压力打开的方式抵住作用于填充喷嘴的液体的重力而保持阻尼，液体被强制地从计量缸充入到填充喷嘴中的液体;以及闭合装置，其适于在液体停止充电时适于作用于处于其打开状态的阻尼器以关闭阻尼器，并且适于失去动作传递关系与阻尼器一起使得弹簧仅在随后开始充注液体之前将阻尼器保持在关闭状态。关闭装置包括用于减轻作用在阻尼器上的冲击的缓冲器和当阻尼器关闭时的阻尼器操作构件。
