ABSTRACT:
A liquid dispensing system including a liquid supply manifold connected to a liquid dispensing reservoir. A check valve is interposed between the manifold and the reservoir to permit liquid flow from the manifold to the reservoir and to prevent reverse flow from the reservoir to the manifold. A dispenser outlet is connected to the reservoir and a dispenser valve is provided thereat to control liquid flow from the dispenser outlet. A source of air under pressure is connected to the reservoir and a control valve is provided to alternately place the reservoir into communication with the source of air under pressure and then subsequently cut off the source of air pressure and place the reservoir into communication with the atmosphere. During the period the reservoir is placed in communication with the air under pressure, the liquid dispenser valve is opened to thereby cause a quantity of liquid to be dispensed from the reservoir out through the dispenser outlet.
The manifold assembly includes a plurality of liquid containers connected thereto with the container closest to the reservoir being at a lower elevation than the next adjacent container and so on up the line to the last container which is located at the highest elevation. The end of the reservoir adjacent the last container is open to the atmosphere. With this arrangement liquid flowing from the manifold to displace the liquid dispensed from the reservoir will be supplied first from the container at the highest elevation and then from the container at the second highest elevation and so on down the line to the container at the lowest elevation.
