ABSTRACT:
A snorkel and buoyancy control apparatus is provided for a snorkeler who employs a snorkel tube assembly for receiving inhaled air. The snorkel and buoyancy control apparatus includes a mouthpiece/selector valve assembly, connected to the snorkel tube assembly, for receiving inhaled air from the snorkel tube assembly and for selectively directing exhaled air to either a one-way valve assembly, e.g. flapper valve assembly, or to a buoyancy control vest. The mouthpiece/selector valve assembly includes a selector valve assembly and a mouthpiece assembly which are connected together. The selector valve assembly includes a first manually-actuated output port selector assembly which enables selective direction of exhaled air either to the flapper valve assembly or to the buoyancy control vest. The flapper valve assembly permits one-way flow of exhaled air from inside the selector valve assembly to outside the selector valve assembly. The buoyancy control vest is connected to the selector valve assembly for selectively receiving exhaled air based upon selective operation of the first manually-actuated output port selector assembly. The snorkel tube assembly may be connected to a selector valve assembly portion of the mouthpiece/selector valve assembly. Alternatively, the snorkel tube assembly can be connected to a mouthpiece assembly portion of the mouthpiece/selector valve assembly.
