Abstract
A fresh air snorkel assembly (10) comprises a breathing tube (12) having a mouthpiece (18) at one end of the tube and an air intake opening (16) at the other end of the tube. The breathing tube (12) further includes an exhaust valve (22) disposed between the mouthpiece (18) and the air intake opening (16), and an intake valve (20,24) disposed adjacent to the air intake opening. The intake valve (20,24) includes floating intake valve means (24) for moving totally toward and away from the valve seat (20) for opening and closing the air intake opening (16) in response to the breathing of the diver. The air intake end of the snorkel is curved so that the air intake opening (16) faces the waterline.
