Buoyancy compensator and inflation system

A buoyancy compensator and filling means therefor comprising:

• a buoyancy compensator having a casing;
• a bladder filling said casing for inflation;
• a port connected to said bladder;
• a conduit adapted for connection to the exhaust gases of a second stage breathing gas regulator and said port;
• and,
• means for valving gas into said buoyancy compensator through said exhaust conduit.

Apparatus to divert exhaust breathing gas that would be normally exhausted from a second stage breathing gas regulator to a buoyancy compensator for an underwater diver comprising:

• a conduit connected to the casing of said second stage regulator;
• means for valving the flow of gas from the casing of said second stage regulator into said conduit;
• and,
• means for connecting said conduit to a buoyancy compensator so that the exhaust gas from said second stage regulator can flow into the buoyancy compensator and cause the inflation thereof.

The combination of a second stage breathing gas regulator for an underwater diver and means for filling a buoyancy compensator comprising:

• a second stage regulator for breathing gas having a casing;
• means for providing gas to said casing;
• means for valving gas into said casing from a high pressure source;
• and,
• mouthpiece means connected to said casing for providing a user with breathing gas that has been valved by said valve;
• a conduit connected to said casing for diverting exhaust gas after it has been breathed;
• means for valving exhaust gas for flow through said conduit;
• means for connecting said conduit to a buoyancy compensator to cause said buoyancy compensator to be filled by exhaust gas from said second stage regulator.
