Abstract
An improved apparatus and method for dispensing beverage syrup is disclosed characterized by use of a low flow rate, positive displacement pump adapted to accurately deliver syrup from a collapsible bag/box syrup container to a dispensing nozzle. Air ingestion into the dispensing system is eliminated by use of a novel air trap/filter adapted to generate a high vacuum signal at the intake port of the pump in response to detecting the presence of air or encountering a syrup depletion condition which signal automatically discontinues pump operation. A vacuum actuated diverter valve is additionally incorporated into the dispensing system to permit the intake port of the pump to be automatically placed in flow communication with differing syrup containers, thereby allowing continuous syrup dispensing operation even during replacement of spent syrup containers.
