Multi-flavor mechanical dispensing valve for a single flavor multi-head beverage dispenser

Abstract

For retrofitting to a backblock of an existing multi-head, multi-backblock beverage dispensing machine, Applicant provides a valve having, in one embodiment, walls adapted to fluidly engage a backblock. A primary circuit has a pair of primary circuit pathways adapted to receive pressurized syrup and pressurized water from the backblock. The valve provides a multiplicity of supplemental circuit pathways adapted to receive (typically not from a backblock) a multiplicity of different syrups from a multiplicity of different pressurized syrup sources. Flow control elements in the valve engage the circuits to control the rate of flow of fluid therethrough. Operator pushbutton controlled valved chambers open and close the circuit pathways. A post-mix valve assembly mixes a syrup from a circuit pathway with the pressurized water from the primary circuit.
