Gas generator
First Claim
1. A gas generator for generating gas under pressure comprising:
- means for providing a first gas including a pressure vessel containing the first gas, the first gas being an oxidizing gas;
means operatively connected with the means for providing a first gas for providing a second gas adapted to be oxidized by the first gas, the means for providing a second gas including a pyrotechnic charge for generating the second gas when ignited;
means for providing an oxidation zone operatively connected with the means for providing a first gas and the means for providing a second gas and including an outlet, the first gas and the second gas being adapted to undergo an oxidation reaction in the oxidation zone for generating the gas under pressure;
means operatively connected with the means for providing the oxidation zone for directing the first gas and the second gas to the oxidation zone such that oxidation zone contains a mixture of the first gas and the second gas for the oxidation reaction thereof, the second gas being of a sufficiently elevated temperature to initiate the oxidation reaction in the oxidation zone; and
back-up catalytic means disposed in the oxidation zone for ensuring initiation of the oxidation reaction of the mixture in the oxidation zone.

Abstract
A gas generator for generating gas under pressure. The gas generator comprises a device for providing a first gas including a pressure vessel containing the first gas, the first gas being an oxidizing gas; a device for providing a second gas adapted to be oxidized by the first gas and including a pyrotechnic charge for generating the second gas when ignited. An oxidation zone of the gas generator includes an outlet, the first gas and the second gas being adapted to undergo an oxidation reaction in the oxidation zone for generating the gas under pressure. The first gas and the second gas are directed to the oxidation zone such that the oxidation zone contains a mixture of the first gas and the second gas for the oxidation reaction thereof, the second gas being of a sufficiently elevated temperature to initiate the oxidation reaction in the oxidation zone. A back-up catalytic device ensures initiation of the oxidation reaction of the mixture.

11. A gas generator for generating gas under pressure comprising:
-
a first vessel containing a first gas, the first gas comprising oxygen; a second vessel operatively connected with the first vessel and containing a second gas adapted to combust with oxygen; means for providing a combustion zone operatively connected with the first vessel and the second vessel and including an outlet, the first gas and the second gas being adapted to undergo combustion in the combustion zone for generating the gas under pressure; means operatively connected with the means for providing the combustion zone for directing the first gas and the second gas to the combustion zone; an igniter operatively connected with the means for providing the combustion zone for activating the means for directing to direct the first gas and the second gas to the combustion zone for combustion thereof for generating the gas under pressure; and catalytic means disposed in the combustion zone for ensuring initiation of the combustion in the combustion zone. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
