ABSTRACT:
An apparatus for providing water and syrup in a predetermined ratio to a beverage dispenser comprises a housing, a source of syrup in a flexible container and a source of water under pressure. A proportioning pump in fluid communication with the syrup source and the water source is provided for receiving syrup and water and for discharging the syrup and water in a predetermined ratio. A water valve, movable between an open and a closed condition, is connected between the water source and the proportioning pump for controlling the flow of water to the pump. The water valve is normally closed, but is opened upon activation of the beverage dispenser, permitting water to flow from the water source to the proportioning pump. Upon receiving the water, the proportioning pump draws syrup from the syrup source and discharges the water and syrup in a predetermined ratio to the beverage dispenser. a vacuum switch, including a sensor, is connected between the syrup container and the proportoning pump. The sensor senses the presence of vacuum in the syrup container, indicating that the syrup in the container has been depleted below a predetermined syrup limit. When the vacuum sensed exceeds a predetermined vacuum limit, the water valve is disabled to prevent water from flowing to the proportioning pump.
