Abstract
A diving snorkel is provided comprising a mouthpiece assembly attached to a breathing tube. First and second purge valves are located in a side wall of the mouthpiece assembly. A partition is disposed in the side wall, between the two purge valves, so as to partially divide the breathing chamber into first and second sections. The first section includes the first purge valve which lies directly in the path of air exhaled from the diver's mouth. The second section contains the second purge valve which is blocked from the direct flow path of the air from the diver's mouth by the partition but does receive some air which flows around the end of the partition into the second section. The partition is inclined so as to direct water to flow, by force of gravity, from the first section to the second section. Another surface directs water within the second section towards the second purge valve.
