Abstract
A beverage making and dispensing apparatus comprising a pressurized water supply; a non-pressurized beverage syrup supply; a hydraulically driven proportional pump with water and syrup inlets connected with the water and syrup supplies, water and syrup outlets connected with a water delivery line and a syrup delivery hose; an aspirator-atomizer mixing device with an elongate mixing chamber with an outlet end, a water passage with an inlet end connected with the water delivery line and a nozzle end to direct a jet of water longitudinally of the chamber toward its outlet end, a syrup port communicating with the chamber and connected with the hose; a water valve to start and stop the flow of water from the pump into and through the mixing device; and, a flow control device in the hose downstream of the pump and upstream of the syrup port to establish a pressure drop and maintain a positive pressure at the syrup outlet of the pump that is less than the minus pressure at the syrup port and a pressure at the syrup port that is less than the water pressure at the nozzle end of the water passage.
