Abstract
A pressure regulator that regulates the pressure at which carbon dioxide is introduced to water in a carbonated beverage system based on the temperature of the water. The regulator may be capable of operating in a first mode in which the carbon dioxide pressure varies substantially linearly over a first water temperature range, and a second mode in which the carbon dioxide pressure is substantially constant over a second water temperature range. A first flow path having a relatively small gas flow capacity may serve as a pilot to control the gas flow through a second flow path having a larger gas flow capacity.
