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).

A valve device for mixing and dispensing beverages of the type which includes a housing having a mixing and dispensing chamber, an entrance port formed in said housing for the admission of a mixing fluid into said chamber, valve means controlling flow through said entrance port, and operator means for operating said valve means, wherein said device comprises: a mixing and dispensing chamber wherein said mixing fluid and a flavored syrup are mixed for dispensing from said device; a valve outlet communicating with said chamber for admitting said flavored syrup to said chamber; said valve means including a ported valve body including first valve port means communicating with said chamber on an outlet side of said entrance port, and a second valve port means in fluid communication with a source of mixing fluid on an inlet side of said entrance port; a flow passage formed in said valve body for delivering a flow of fluid from said second port means to said first port means; a hollow valve stem carried by said valve body having an internal bore, a valve rod carried in said internal bore, said internal bore being open on both ends permitting adjustment and reciprocation of said rod lengthwise therein; a space defined between said flow passage and an end of said valve rod; and means for adjusting the position of said end of said rod in said space to open and close said space and hence adjust the flow rate of said mixing fluid through said entrance port.
