The invention relates to the means of diving at small depth with short stay time under water. A breathing apparatus for diving contains at least one air flask and a valve box connected with a hose of inhale and a hose of exhalation. The flask inside is divided by a sealed mobile partition with formation of a cavity for carbon dioxide and a cavity for air. In the partition an one-sided controlled valve is installed. The partition is connected by an elastic rope with a spring-loaded plate, which is capable of reacting on the ambient pressure from one side and on the pressure in the cavity for carbon dioxide from other side. The hose of inhale is connected with the cavity for air, while the hose of exhalation - with the cavity for carbon dioxide. Both hoses are made with possibility of connection with atmosphere through an appropriate controlled inlet and release valves. The possibility of automatic filling the flask with air during each diving of user is a technical result. |
