ABSTRACT:
An improved carbonated beverage mixing and dispensing valve (A) is illustrated as including a housing (10) having an entrance port (16) for the admission of carbonated mixing water and valve outlets (22a) for admitting flavored syrups. A valve (B) is carried in the entrance port for controlling the flow of carbonated water which includes an adjustable metering rod (20) carried in an internal bore (104a) of valve stem (104) which may be adjusted externally of housing (10). Flow of syrup is controlled through valve outlet (22a) by means of flow control device (C) which includes a raised ridge (44a) and valve plunger (46) between which a section of valve tubing (22) is pinched off intermediate a valve inlet (30a) and valve outlet (22a). A single operator lever (92) operates both the valve (B) and flow control device (C) in a single action. A rotatable selector plate (62) carries a cam (D) having camming portions (72, 78, 74) which engage respective plunger heads (46a, b, c, d) to actuate any one of four plungers (46) and permit flow through a respective valve tube (22). Cam plate (D) includes position notches (82, 84, 86, 88) which correspond to plunger positions and cooperate with a post (90) carried by lever (92) to indicate and assure proper position of the selector plate/knob at a desired syrup selection and actuating position therefore. Pivoting of lever (92) to the dotted line position (92b) causes reciprocation and opening of valve (B) through engagement of valve stem (104) and lever end (92a) while a selected plunger is actuated by engagement of a plunger head and cam portion and axial movement of selector plate (62) by engagement with post (90) during pivoting of lever (92).
