A beverage dispenser valve system in which the mixture ratio is controlled by continuous modulation of the solenoid valves. The solenoid valves have movable stop (or push rods) that control the travel of the armature, which in turn controls the position of a needle valve with respect to the valve seat to gradually change the flow opening and thus the syrup and water flow rates. A microprocessor uses the movable stop to adjust the syrup and/or water flow rate to deliver the proper ratio of syrup to water based on the flow of water and syrup as measured by flow meters. In addition, the total flow rate from the nozzle can be controlled and varied in relation to the distance the cup lever arm is depressed; thus, the flow rate can be made slow at the beginning and end, and fast in-between.
A beverage dispenser valve comprising:
In a solenoid valve for use in a post-mix beverage dispenser valve and including a coil, an armature tube, an armature movably positioned in said armature tube, a spring biasing said armature toward its de-energized position, and a valve member at the distal end of said armature, the improvement comprising:
