Abstract
A gas generator and a method of generating a gas are provided. A gas generator includes a cartridge having a solid reactant and a liquid reactant distributor provided therein, and a liquid reactant supply in fluid communication with the liquid reactant distributor. The liquid reactant supply is configured to provide a liquid reactant under pressure to the liquid reactant distributor. The liquid reactant distributor comprises a plurality of normally closed holes configured to open at a predetermined fluid pressure to disperse the liquid reactant for reaction with the solid reactant in the cartridge.

A gas generator comprising:
- a cartridge having a solid reactant and a liquid reactant distributor provided therein;
- and
- a liquid reactant supply in fluid communication with the liquid reactant distributor and configured to provide a liquid reactant under pressure to the liquid reactant distributor;
- wherein the liquid reactant distributor comprises an elastic tube of an elastic material, the liquid reactant distributor having an outer diameter and an inner diameter and a plurality of holes along its length, wherein a wall thickness of the liquid reactant distributor is defined by a ratio of the outer diameter to the inner diameter, wherein the elastic material, the wall thickness and a diameter of the holes (hole diameter) are configured such that the plurality of holes are closed when the liquid reactant distributor is below a predetermined fluid pressure and are opened when the liquid reactant distributor is at or above the predetermined fluid pressure to disperse the liquid reactant for reaction with the solid reactant in the cartridge.
