Snorkel and buoyancy vest with manual controls

摘要

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. Air directed to the buoyancy control vest is used to inflate the buoyancy control vest. The selector valve assembly may also include a mode for connecting the buoyancy control vest to the vent to deflate the buoyancy control vest.
