Abstract
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.
