Abstract
In order to fill an inflatable safety restraint device such as an air bag, a relatively small pyrotechnic charge is used to pressurize a chamber of water or other suitable liquid and force the liquid out of the chamber and through a conduit in a manner wherein it is caused to intimately mix and atomize in a high speed stream of gas resulting from the combustion of the pyrotechnic charge. The heat of the combustion gas is absorbed by the liquid which is then converted into a large volume. The vaporized liquid and combustion gas is used to inflate the air bag with an essentially non-toxic, low temperature, low particulate atmosphere. The resulting combustion gas and liquid mixture may also be used to extinguish a fire.
