ABSTRACT:
A compact and smoothly working, principally electrically controlled beverage mixing and dispensing system is provided in which water or carbonated water is supplied as the principle ingredient and one or more, usually two, sub-ingredients, such as syrup, flavoring extracts, sweeteners, etc. are to be separately supplied in selected, regulated amounts, mixed therewith and then discharged into a suitable drink container. Pumps illustrated are fluid pressure (carbon dioxide) operated to supply the sub-ingredients to individual electric switches and then through individual regulators and electric solenoid-controlled valves into a common mixing and drink dispensing chamber. Each electric switch is fluid pressure sensitive and normally closed to energize the solenoids and open their associated valves when a positive pressure flow of a liquid ingredient is being supplied from a suitable source; and each switch is opened when a fall-off or negative fluid pressure is applied thereto due to a depletion or shut-off of flow of any one of the ingredients, and is employed to, when moved to an "open" position, simultaneously cause a de-energization of all the solenoids, a closing of their associated valves and a stoppage of any feed of ingredients into the mixing chamber.
