Abstract

A closed or semi-closed breathing system for smoke diving and the like includes a pneumatically controlled breathing bag (1) communicating in a circulation (4, 5, 6) with a breathing mouthpiece or breathing mask (2) for a user and with an absorption means (3) for exhaled CO2, a pneumatic actuator (9) arranged for alternating expansion and contraction of the breathing bag (1) in accordance with the breathing pattern of the user, and a pressurized gas source (11) coupled to the breathing bag (1) to supplement the breathing gas therein. The system includes a mode regulator (10) arranged to control the actuator's actuation of the breathing bag (1) while simultaneously maintaining an overpressure in the breathing mask (2) in relation to the surroundings, and a dosing means (13) for the supply of a metered gas quantity to the breathing bag (1) in dependence on its degree of filling.
