Abstract

A self-contained underwater breathing apparatus wherein surface air is delivered through a float-supported hose to a compressor carried by the diver and powered by the diver's exhalations. The compressed air is stored in reservoirs and inhaled by the diver through a demand regulator. An auxiliary manually powered compressor is provided for startup, emergency use and to make up system losses.
