Abstract
A CO.sub.2 gas generator for a utilization device is located in a housing and chemically generates CO.sub.2 from a chemical reaction between two reagents contained within a common container. The reagents are located in different chambers of the container with a CO.sub.2 accumulation region being included in one of the chambers. A reference pressure source of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the CO.sub.2 accumulation region is less than the predetermined pressure whereupon CO.sub.2 is generated in one of the chambers. An output conduit in fluid communication with the CO.sub.2 accumulation region is provided to withdraw the generated gas from the generator. As the CO.sub.2 is withdrawn, the gas pressure drops permitting more mixing of the reagents. When the CO.sub.2 pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separated again and gas generation ceases.
