Abstract
A diving snorkel is provided with a purge valve located in a branch or bypass conduit. The branch conduit connects with the main snorkel conduit at a place remote from the mouthpiece. When the diver resumes a snorkel attitude after the snorkel has been filled with water, the purge valve allows water in the projecting end of the snorkel to drop to the level of the water surface, minimizing the amount of water required to be purged for snorkel breathing. The remote location of the purge valve provides efficient utilization of exhalation effort.
