摘要

A post-mix beverage dispensing valve for dispensing syrup and soda in the desired ratio without the need for flow controls for periodic adjustment of the ratio. The valve includes a flow meter (30) for measuring the flow rate of the soda and a pump (10) for dispensing metered quantities of syrup. The pump (10) preferably includes a chamber (14) within a ceramic sleeve (12) having first and second distal ends and a double-acting ceramic piston (16) mounted for reciprocating sliding movement within the sleeve (12). A solenoid valve control system including a pair of solenoid valves (SCA, SCB) controls syrup flow through the pump (10), in response to signals from the flow meter (30). The valve preferably also includes a syrup flow regulator. The valve can include a single externally manually adjustable flow rate control to vary the dispensing flow rate to any desired value.
