Abstract
An airbag inflator () has an inflator housing () with an internal chamber (); a pyrotechnic gas generant () stored in the internal chamber inside the housing () for generating inflation gases upon ignition; a strainer () with openings through which the inflation gases pass prior to inflating the airbag; a primary nozzle wall () positioned between the strainer and the gas generator; a plenum chamber () between the primary nozzle wall () and the strainer (). The primary nozzle wall () has a plurality of nozzles () with nozzle openings () oriented radially about the wall which directs gas flow tangentially spiraling laterally onto the strainer while preventing the inflation gas from flowing radially. The tangentially flowing gases impinge an internal face of the strainer laterally causing gas generant particles to recirculate and burn internally and residual debris of a size greater than the openings of the strainer () to be swept and settle in the plenum chamber () of the housing.
