ABSTRACT:
A gas generator comprising a housing having a mixing chamber and a pyrotechnic charge in the housing. A container having a liquid therein is disposed in the housing and has an open end and a closed end, with an end cap closing the open end and having a piston portion removably connected thereto and being movable within the liquid container to pressurize the liquid therein when the piston portion is separated from the end cap. The piston portion is positioned to be exposed to combustion gas from the pyrotechnic charge when it is ignited and is separable from the end cap when the combustion gas exceeds a predetermined pressure. In another embodiment, the liquid container may be a collapsible tube. The closed end of the liquid container has a weakened portion constructed to be opened when the pressure of the liquid in the container exceeds a predetermined pressure. The pyrotechnic charge and the weakened portion of the liquid container are in fluid communication with the mixing chamber so that combustion gases from the ignition of the pyrotechnic charge mix with and vaporize the liquid in the mixing chamber to generate a non-toxic, low temperature, low particulate inflation gas.
