UNDERWATER RESPIRATORY APPARATUS Russian patent published in 2004 - IPC

FIELD: production of underwater respiratory apparatuses.

SUBSTANCE: the invention presents an underwater respiratory apparatus containing a working unit with a chemical source of oxygen, a breathing mask and a respiratory hose connecting the mask with the working unit. The working unit made in the form of a container open from below is supplied with: a located in the upper part of this container lattice for accommodation of a chemical source of oxygen in the form of a briquette of the substance generating oxygen at its interaction with water; a stabilizer of a vertical position; an indicator of the oxygen source exhaustion and a gas discharge tap for the respiratory tube. The stabilizer of a vertical position is made in the form of a tube with a gas container on its upper end and the transparent lower end. The indicator of the oxygen source exhaustion is located in the mentioned above transparent part of the tube and is pressed by a spring to the upper butt of the indicated briquette. Such design of the apparatus ensures decrease of its mass-volumetric performances, reduction of a range of spent products, simplification of their composition and indication of the product exhaustion.

EFFECT: the invention ensures decrease of the apparatus mass-volumetric performances and a range of spent products, simplification of their composition and indication of the product exhaustion.
