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 lower portion through a passage which may be regulated in size by the amount of threading of the cover onto the hub portion. The spaces between the partition walls open outwardly and they provide a sound absorber.
