ABSTRACT:
A snorkel for use in swimming. The snorkel includes an elongate breathing tube having an upper portion and a lower portion. A lower opening is formed in the lower portion and an upper opening is formed in the upper portion. A mouthpiece is located at the lower opening of the snorkel. A one-way valve is disposed in the lower portion and is oriented to prevent the flow of fluids into the lower portion, but to permit the flow of gases and fluids out of the lower portion. A check valve is disposed in the upper portion. The check valve includes a plate pivotable from an open position permitting airflow through the upper opening, to a closed position preventing airflow through the upper opening. A spring member contacts the plate, biasing the plate in the open position.
