Abstract : This patent discloses low temperature inflator assembly for an inflatable life raft or life preserver for ensuring sufficient buoyancy in low ambient temperatures. A CO2 cartridge and a solid pyrotechnic gas generator are positioned side-by-side in a heat transfer housing. A single actuator punctures the cartridge and ignites the generator. Combustion gas from the generator supplies immediate low pressure inflation while heat transferred from the generator to the cartridge accelerates a subsequent high pressure source of CO2. Higher gas capacity and pressure are obtained with no tradeoff of total size compared to the conventional CO2 cartridge inflators. Keywords: Carbon dioxide; Gas generating systems; Inflating.
