Abstract [en]

A rechargeable breathing apparatus with a closed breathing system, particularly for aqua-diver. It comprises a breathing bellows (28) for reception of the exhaled air, to which bellows a pressurised container (38) for a gas or a mixture of gases is connected through a hydrostatic valve (42). The breathing bellows is arranged, after adsorption of CO2 from the exhaled air, and oxygen supply, to deliver breathing air to the diver. An oxygen accumulator (12) containing a reversibly oxygen fixating agent is connected to the breathing bellows (28). The oxygen accumulator (12) is rechargeable by bringing said agent into reaction with oxygen gas or oxygen in the air whereby the oxygen is adsorbed to the same. An oxygen accumulator (12) upon heating gives off oxygen to the breathing bellows. The apparatus may also be used during smoke divin
