ABSTRACT:
A liquid proportioning system is disclosed which operates to mix a liquid concentrate and a liquid diluent in predetermined ratios. The system includes an automatic valve to terminate the flow of concentrate in the event that an insufficient supply of diluent exists. In addition, an anti-siphoning system is disclosed for creating an anti-siphoning air bubble at the upper end of the diluent reservoir and for insuring that such air bubble is not lost in the event of leakage around the filler cap.
