SOLID PROPELLANT GAS GENERATOR

摘要

SOLID PROPELLANT GAS GENERATOR A gas generator includes an annular hermetically sealed combustion chamber containing a charge of propellant and an initiator. The combustion chamber is enclosed within a circular inner housing having peripherally spaced groups of openings. Disposed radially of each group of openings is a roll of filter screen wrapped about a central neutralizer core. An outer housing includes two members, each member having three spaced circular embossments. The embossments open to each other and define circular enclosures when the housing members are abutted. One enclosure encapsulates the combustion chamber and inner housing. The other enclosures encapsulate respective rolls of filter screen. The embossments of the housing members are interconnected by grooves which open to each other and define passages connecting the enclosures when the members are abutted. Additional grooves in the members define passages connecting the screen enclosures with an article to be inflated.
