US Patent 11702331 Beverage dispensing machines with dispensing valves

A beverage dispensing machine includes a dispensing valve having a first flow path configured to dispense a first fluid and a second flow path configured to dispense a second fluid such that the first fluid and the second fluid mix downstream and form a mixed beverage. A flow control device regulates flow rate of the first fluid through the first flow path, and a shutoff valve selectively closes to stop flow of the first fluid through the first flow path. A sensor is configured to sense the flow rate of the first fluid, and a controller automatically controls the flow control device to adjust the flow rate of the first fluid and thereby obtain a desired fluid ratio of the mixed beverage.
