Definitions

  • the invention relates to a fresh air snorkel which make it easier for the diver to breathe.
  • a conventional snorkel has only one tube, resulting in the diver inhaling used air remaining in the tube.
  • FR-A-736 745 a fresh air snorkel according to the first part of claim 1 is known.
  • the one-way valves are both arranged in the free end of the outlet tube resulting in an inefficient air exchange during breathing.
  • the fresh air snorkel will give as result that the diver does not need to breathe so deeply to gain fresh air, and that the diver will not be so quikly exhausted.
  • the fresh air snorkel can be made twice as long as a conventional snorkel and the diver need not to breathe deeper to gain the fresh air.
  • One of the tubes leads air to the diver and the other tube leads air from the diver.
  • a one-way valve which opens only while the diver inhales and another one-way valve which opens only while the diver exhales.
  • a mouthpiece 3 connected at 4 to a middel-piece 7, which is divided into two separate air tubes 5,6, one inlet air-tube 5 and one outlet air-tube 6. These are in their whole length arranged close to each other. Both tubes are approximately of the same length.
  • one-way valves 1, 2. These valves are constructed so that one valve opens at inlet breathing, and the other opens at outlet breathing.
  • Fig. 2 shows that the valves are fitted in the free end of the tubes but other arrangements are possible.
  • the valves can be fitted in the opposite end, at 4, not shown in the figure. It is also possible to place several valves in each tube, for example one valve fitted in both ends in each tube.
  • the diver While using the fresh air snorkel, the diver may continously hold his mouth closed around the mouthpiece, while fresh air and used air may pass through the mouthpiece.
