Abstract
A nozzle for a post-mix beverage dispensing valve is shown for optimizing flow at flow rates above 3.5 oz./sec. The nozzle includes a first diffuser plate followed by a central flow piece having a frusto-conical outer water flow surface and an interior syrup flow channel. Second and third diffuser plates follow the frusto-conical portion. The second and third diffuser plates have perimeter edges that contact the inner surface of a nozzle housing so that the carbonated water must flow through holes in the diffusers. In this manner the gradual reduction of pressure of the carbonated water to atmospheric can be controlled in part by increasing the surface area of the holes in each successive diffuser.
