Abstract
A method of manufacturing a chemical oxygen generator using two plates and a chemical substance which produces oxygen through a chemical reaction and an isostatic pressing device, comprising, forming at least one depression between two flat portions of each plate, placing the plates together by superimposing their flat surfaces together in the isostatic press, and arranging their depressions so that they oppose each other, and filling the depressions with the chemical by inserting the chemical axially into the depression and deforming the plates by pressing the pressing device to close the depressions along the flat surfaces at each end and to compress the chemical within the depressions. The invention construction advantageously includes plates having two sets of depressions or one continuous serpentine depression in each plate, which are arranged in mirror orientation and closed at one end and contain an ignition device for the chemical at the opposite end.
