Abstract
Apparatus for admitting metered quantities of a liquid into discrete containers in the form of bottles, cans or the like has a rotary annular tank which carries at its underside a ring-shaped set of filling units each of which has a discrete metering vessel serving to receive a metered quantity of liquid from the interior of the tank for admission into a container which is placed into alignment with a centering and sealing sleeve movably mounted on each metering vessel. If the liquid is to be admitted into the containers at an elevated pressure, the supply of liquid in the tank is disposed beneath a plenum chamber and each filling unit is designed to admit compressed gas from the plenum chamber into the aligned container prior to admission of a metered quantity of liquid. The liquid which flows into a container expels the compressed gas which is returned into the plenum chamber or into a separate receptacle. The liquid-receiving capacity of the metering chamber in each vessel can be varied by an adjustable insert which can be manipulated from above the tank. The metering vessels can be located beneath the bottom wall of the tank or an upper section of each metering vessel can extend into the tank.
