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.

Abstract: A new and improved snorkel and buoyancy control apparatus includes a snorkel tube for receiving inhaled air, a first one-way air valve connected to the snorkel tube for permitting air flow into the snorkel tube during inhalation, and a mouthpiece for receiving inhaled air and for supplying the inhaled air to the snorkeler's mouth and lungs. The mouthpiece includes a mouthpiece output port for permitting exhaled air to exit from the snorkeler's mouth. A second one-way air valve is connected to the mouthpiece for permitting air flow from the mouthpiece to a selector valve assembly. The selector valve assembly, connected to the mouthpiece by way of the second one-way air valve, receives exhaled air from the mouthpiece and selectively directs exhaled air to either a first selector valve output port connected to a vent or to a second selector valve output port connected to a buoyancy control vest which includes a first port connected to the selector valve assembly.
