Abstract
A pyrochemical gas generator, comprises a cylindrical receptacle which includes a hollow cylindrical bottom portion having an interior bottom wall with a plurality of individual cylindrical recesses for receiving individual charges defined directly on the bottom wall. The bottom wall also includes annular grooves which interconnect the recesses and provide a gas passage after ignition of the charges. The bottom includes a central upstanding hub portion and a firing plate which has an apertured hub portion is disposed over the bottom and its hub portion is spaced from that of the bottom to define a primer charge chamber therebetween in which a primer charge is positioned. An intermediate housing which has a lower cylindrical portion is engaged over the firing plate and around the periphery of the bottom portion and it has a dividing wall with a plurality of upstanding partition walls. A top cover is engaged over the intermediate housing by being threaded onto the hub portion and it has a plurality of depending partition walls which are located between the upstanding walls of the intermediate housing. The spaced apart partition walls define gas passes which are communicated with the …
