2. Description of the Related Art

Currently restaurants serve a variety of beverages such as carbonated drinks and non-carbonated drinks by use of beverage valve assemblies. The beverage valve assemblies, for example, a plurality of beverage valve assemblies 1100a, 1100b, 1100c and 1100d shown in FIG. 1, mix and dispense carbonated and non-carbonated beverages. Plurality of beverage valve assemblies 1100a, 1100b, 1100c and 1100d are similar to one another, and, accordingly, only one of the plurality of beverage valve assemblies 1100a is described herein. Beverage valve assembly 1100a has a cover 1102 that covers controls (not shown) and valves connected to a valve body (not shown) that control and mix flavor ingredients, for example, cola or lemonade, and carbonated water and/or still water to form a beverage. Cover 1102 protects internal valve assembly components such as solenoids, flow controls, electronics, and the like. Beverage valve assembly 1100a has a nozzle 1104 and lever 1106. A force is applied to lever 1106 to move lever from front to back to actuate a control to mix flavor ingredients and carbonated water and/or still water to form the beverage and dispenses the beverage through nozzle 1104 into a container such as a cup as is known in the art. Beverage valve assembly 1100a has a beverage valve assembly housing 1108 having a dispenser wall connected to beverage valve assembly 1100a and a surface 1110 adjacent cover 1102 forming an upper space 1112 therebetween. Beverage valve assembly housing 1108 forms a lower space 1113 below nozzle 1104.

FIG. 2 is another exemplary embodiment of a plurality of beverage valve assemblies 1200a and 1200b. Beverage valve assemblies 1200a and 1200b are similar to beverage valve assembly 1100a, and, thus, similar features include the same reference numerals. Each of beverage valve assemblies 1200a and 1200b has beverage valve assembly housing 1108 having surface 1110 adjacent cover 1102 forming a space 1112a therebetween.
