ABSTRACT:
An electrically operated valve for effecting diffusion of a flow of pressurized diluent to substantially atmospheric pressure and mixing the diluent with a gravity flow of beverage concentrate in controlled proportions and dispensing a mixed beverage therefrom by gravity flow. Separate valving chambers are provided for the diluent and the concentrate flow and the valves are individually actuated by electric solenoids. A removable nozzle assembly is provided which includes a removable thin orifice plate for metering the flow of the concentrate for effecting complete mixing. A pressure responsive device is provided to give additional force biasing the concentrate valve to the closed position, thereby permitting the use of concentrates containing pulping liquid. A cross-flow passage is provided between the inlets for the diluent and concentrate valving chambers in order that opening of the diluent valve will drop the pressure on the pressure responsive device and permit the solenoid to open the concentrate valve. The valving chambers are formed of thermally insulating material, and tubular projections formed of heat conducting material are provided at the inlet of each valving chamber. The tubular projections terminate closely adjacent the valving chamber and permit the diluent and concentrate to be maintained at the desired temperature in the proximity of the valving chamber, such that upon opening of the dispensing valve, the initial mixed beverage is at the desired temperature.
