Abstract
In a carbonated beverage dispensing apparatus including a dispensing valve, carbon dioxide gas is introduced into a liquid to be dispensed through the dispensing valve, and a temperature sensor is arranged to sense the temperature of the liquid, either in a carbonation tank or in the path through which the liquid is fed to the carbonation tank. A control, responsive to the temperature sensor, controls a valve which regulates the pressure at which carbon dioxide is introduced into the liquid. The carbon dioxide pressure increases with increasing liquid temperature, so that the carbonation level in the liquid dispensed through the dispensing valve is maintained at a substantially constant level. Both mechanical and electronic controls are disclosed.
