Abstract
A device for generating oxygen by the thermal decomposition of a chemical contained in a cartridge housing, whose reaction takes place, beginning from an activation point, along a reaction front propagating in the interior of the cartridge housing in the direction of an unspent chemical, with a feed line with a restrictor, which feed line originates from the cartridge housing from the area of the unspent chemical in front of the reaction front, for drawing off the oxygen generated, shall be improved in terms of a more uniform release of the oxygen generated. To accomplish this task, a compensating line, which opens into the interior of the cartridge housing in the area of the spent chemical behind the reaction front, is connected to the cartridge housing.
