FIELD: individual isolating breathing machines, ensuring vital activity of a person under water, possible use by submariners during exit from sunken submarine by free emergence method or buoy line exit, and also for execution of simple diving operations.
SUBSTANCE: underwater breathing apparatus for diving suit contains working block, made in form of a vessel open from below, provided with a grating for placement of a brick of superoxide product, breathing tube and brick consumption indicator, and also portable oxygen gas analyzer. Breathing tube is connected to head part of diving suit, divided on two gas-isolated parts. Second (lower) part of diving suit is connected to head part through gas pass-by valve and filled with air or physiologically indifferent gas (for example, nitrogen, helium or their mixture).
EFFECT: possible automatic correction of composition of gas mixture to match the pressure of external environment in which the diver is located.
