ABSTRACT:
In the containing filling device the tank for the liquid to be dispensed into containers has gas somewhat over atmospheric pressure applied to the liquids surface. Each filling station has an outlet leading to the container being filled, a gas valve coupling the tank to the container and a fluid valve coupling the tank to the conveyor. The liquid above the tip of the tube that leads from the gas valve is forced back into the tank by means of gas pressure injected into the outlet after the filling operation is ended. In which case the fluid valve is forced closed and the gas valve is forced open. Because of the forced open gas valve the injection of gas takes place at very low pressure differential, causing neither disturbance of the liquid in the container and in the tank nor blow out of liquid below the level of the tank of the gas return tube.
