Abstract Appareil respiratoire avec régénération de l'air respiratoire au moyen de plusieurs charges chimiques, délivrant de l'oxygène et liant le dioxyde de carbone, disposées en parallèle dans la voie respiratoire entre un embout respiratoire et un sac respiratoire.Selon l'invention, à cet effet, un propre sac respiratoire 8, 9 est raccordé à chaque charge 3, 4, pour recevoir l'air expiré qui la traverse. A respirator with regeneration of the respired air by several chemical fillings, which emit oxygen and bind carbon dioxide and are disposed in parallel in the respiratory passage between a mouthpiece and a breather bag is to be improved, so that a uniform utilization of the chemicals in the fillings is achieved. The different resistances of the respiratory paths of the fillings are to be evened up so that the pollutant load on and the consumption of the fillings can be divided up evenly over the existing fillings during the whole of the period of use. For this purpose, provisions are made so that each filling is connected to its own breather bag for accommodating the exhaled air flowing through it.
