Patent ID: 8127966

Claim:
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.
