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.

An improved beverage syrup dispensing apparatus comprising: a reservoir adapted to store a quantity of beverage syrup; a nozzle formed to dispense said quantity of said beverage syrup with a proportional quantity of a beverage mixing fluid; a pump disposed between said reservoir and said nozzle for delivering said quantity of syrup from said reservoir to said nozzle; means disposed between said reservoir and said pump for detecting the presence of air in said quantity of syrup; said detecting means comprises a valve including a valve seat and valving member, said valving member adapted to remain spaced from said valve seat when said quantity of syrup is present in said valve to permit said quantity of syrup to flow across said valve seat and contact said valve seat when said quantity of syrup is not present in said valve to prevent any flow of air across said valve; and switching means responsive to said detecting means for automatically discontinuing the operation of said pump upon the detection of air in said quantity of syrup.
