Abstract (en)
[origin: WO9109772A1] The fresh air snorkel for divers and similar users has the effect with the result that the diver breathes easier due to breathing the air in through one tube and breathing air out through the other tube based on that it is installed one or several one-way-valves (1, 2) in each tube. The fresh air snorkel is equipped with one mouthpiece (3) which can be arranged to a middle piece (7), if necessary, or directly to two separate inlet and outlet tubes (5 and 6). The inlet tube and the oulet tube can be constructed close to each other so that another person can close his mouth over both tubes without knowing which tube is the inlet tube.
