Abstract
The specification discloses a diver's snorkel having an elongated tube with a fitting at the end incorporating a mouthpiece. Distal from the mouthpiece is a water drainage purge chamber extending away from the mouthpiece. The entrance conduit interconnecting the elongated tube to the mouthpiece and the purge chamber is at an angle sloping downwardly from the mouthpiece during use. The purge chamber is angled inwardly toward a diver's chin when in use so that the axis thereof is at an angle to the axis of the mouthpiece. The purge chamber has a purge valve distal from the mouthpiece and incorporates a chamber of significant volume for drainage from the mouthpiece and the elongated tube in an unobstructed manner.
