Beverage dispenser system using volumetric ratio control

摘要

The device includes a single piston in a single cylinder, syrup and soda chambers, and self-contained direct acting electrical solenoid valve for controlling the flow through the volumetric ratio control device and the reciprocating action of the piston. The soda pressure drives the piston. This post-mix dispensing valve can be used with any of a figal, a bag-in-box, a gravity tank, or a non-returnable container under no pressure or under a low pressure of 5 to 10 psig. A non-returnable, pressurisable syrup container is also provided. The total volume of the water and concentric chambers is less than about 0.7 fluid ounces.
