FLUID MIXING APPARATUS FOR PRODUCING VARIABLY CARBONATED WATER

摘要

A variable output adjustable carbonator for blending plain and carbonated water at a desired ratio before being mixed with syrup inside the nozzle of a beverage dispenser. The dilution of carbonated water with plain water permits the dispensing of beverages having variable carbonation. Plain and carbonated water traveling in separate conduits enter the adjustable carbonator and follow separate passages inside, each being regulated by an adjustable flow control washer which maintains a constant flow therethrough despite variations in the fluid supply pressure. A needle valve is employed to adjustably restrict flow through each flow control washers, thereby fixing the mixture of plain and carbonated water at a predetermined ratio.
