Abstract
A chemical oxygen generator includes a candle in which oxygen is present and which is chemically combined and which is ignited by starting means to initiate the generation of the oxygen. This takes several seconds before a substantial quantity of oxygen is provided. Because a user of this oxygen must be supplied with the oxygen for respiration immediately, the invention includes a generator which has a pressure space, preferably above, below and around the oxygen candle which is located in the space and which is filled with compressed oxygen. The generator includes a member which is actuated upon release of the starting means for the oxygen to permit outward flow of the oxygen in the pressure space which is supplied until the oxygen being released from the candle is produced by the ignition of the candle.
