Abstract
A closed cycle respirator includes a breathing bag, the bottom of which is in communication with a canister containing a chemical that binds carbon dioxide and water vapor and liberates oxygen. Inside the breathing bag there is a distributor that guides the regenerated respiratory air flowing up from the canister laterally in the direction of the breathing bag's side walls but keeps that air largely away from the side of the bag that lies against the chest of the wearer. The reason for directing the air through the bag in this manner is to reduce the temperature of the air before it is inhaled again.
