A filling apparatus for carbonated beverages including a filling valve connected to a beverage source under pressure and including a measuring cylinder movable into and out of a container to be filled. The measuring cylinder has a foot valve on its lower end and is telescopically associated with an inlet valve. The measuring cylinder defines a chamber between the foot valve and the inlet valve. The measuring cylinder is filled with a predetermined amount of beverage at superatmospheric pressure by moving the cylinder down into an empty container when the foot valve is closed and the inlet valve is open. The inlet valve is then closed. The cylinder and foot valve can then be moved down a slight amount or the foot valve can be moved down a slight amount relative to the cylinder while retaining sealing contact with the cylinder to increase the volume in the chamber thus reducing the pressure of the measured volume of beverage to atmospheric pressure. The foot valve is then opened and the measuring cylinder and foot valve are moved upwardly to transfer the measured quantity of beverage into the container at atmospheric pressure. At the end of the filling cycle, the foot valve is brought into engagement with the inlet valve so that the volume of the chamber is reduced substantially to zero and all of said measured volume of beverage is discharged into the container.

An apparatus for filling a carbonated liquid into a container comprising, supply means for maintaining a supply of carbonated liquid under superatmospheric pressure, means defining a variable volume measuring chamber for receiving and confining a predetermined quantity of liquid at said superatmospheric pressure from said supply means, foot valve means for releasing the liquid from the measuring chamber into a container at atmospheric pressure, said foot valve means including an expansible resilient sealing element for sealing between said foot valve means and said chamber defining means, and means for slightly increasing the volume of said chamber defining means for reducing the pressure of said liquid to about atmospheric pressure, said last named means comprising means for lowering said foot valve means slightly with respect to said chamber defining means to permit said sealing element to be moved vertically while still maintaining its sealing effect with said chamber defining means. An apparatus for filling a carbonated liquid into a container comprising supply means for maintaining a supply of carbonated liquid under superatmospheric pressure; a vertically oriented cylinder connected to said supply means; a foot valve for closing the lower end of said cylinder; a piston mounted for relative movement within said cylinder, said piston and foot valve defining a variable volume measuring chamber within said cylinder for measuring a predetermined charge of liquid for delivery to said container; an inlet valve provided in said piston for permitting flow of said liquid from said supply means to said measuring chamber; means for holding a container to be filled in a position to receive said predetermined charge of liquid from said measuring chamber; and raising and lowering means attached to at least three of said container holding means, said cylinder, said foot valve, said piston and said inlet valve for relatively moving said container holding means, said cylinder, said foot valve, said piston and said inlet valve so that said cylinder is lowered into said container and said inlet valve is closed with said predetermined charge of liquid being in said measuring chamber, said foot valve and cylinder are separated to permit said liquid to flow into said container, said cylinder is raised relative to said container while said container is filled with the lower end of said cylinder remaining beneath the surface of the liquid in the container substantially until the completion of the filling thereof, said cylinder and foot valve are closed and are brought into engagement with said piston to reduce the volume of said measuring chamber substantially to zero, and said inlet valve is opened and said piston is separated from said foot valve to recharge the measuring chamber.
