Abstract
The present invention is a post-mix beverage dispensing valve for accurately maintaining the proper ratio of two liquid beverage components. The present invention includes a valve main body having a gear pump secured thereto. The gear pump includes two sets of oval gears. One set of oval gears is in fluid communication with a source of pressurized carbonated water, and the second set is in fluid communication with a source of syrup. The valve body also includes solenoid operated pallet valves for each of the beverage components. Ratioing of the solenoid provides for simultaneous opening of both pallet valves whereby the pressurized carbonated water flows between the carbonated water gears and is swept thereby through the valve body to the dispensing nozzle. One gear of each gear pair is secured to a common rotating shaft. Pressurized carbonated water provides for the rotation of the syrup gears, thereby providing for the pumping of the syrup to the nozzle. The gear pairs are sized so that the desired ratio between the beverage components is maintained.
