Beverage dispensing system with a head capable of dispensing plural different beverages
First Claim
1. A method of gradually reducing the pressure of a pressurized, carbonated fluid, comprising the steps of:
- injecting a pressurized, carbonated fluid at a first pressure into a discharge head, the discharge head having;
a plurality of fluid passages in fluid communication with a discharge nozzle, the plurality of fluid passages having non-linear flow paths;
a plurality of inlet openings for receiving the pressurized, carbonated fluid; and
a plurality of outlet openings communicating with the discharge nozzle, the plurality of fluid passageways having cross-sectional areas that increase from the plurality of inlet openings to the plurality of outlet openings and wherein the plurality of fluid passageways form a helix;
forming a depressurized, carbonated fluid at a second pressure lower than the first pressure by causing the pressurized, carbonated fluid to flow through the discharge head; and
dispensing the depressurized, carbonated fluid from the dispensing head.

Abstract
A beverage dispensing system includes a base to which a dispensing head is removably attached without additional fasteners. Beverage-forming liquids are supplied through a plurality of separate conduits in the base. Each base conduit has a normally closed valve that normally blocks fluid flow. The dispensing head has at least one passageway that receives liquid from an associated one of the base conduits. A projection associated with each dispensing head passageway opens the associated conduit valve to allow fluid flow from the base to the head. Dispensing valves in the dispensing head regulate the dispensing of the beverage. By selectively opening the dispensing valves, a plurality of beverages are formed from combinations of one or more liquids. A dispensing head includes an inlet opening and an outlet opening at each end of a passage extending through a body, the inlet opening having a smaller cross-sectional area than the outlet opening.
