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.
