Definitions

  • the invention relates to an fresh air snorkelwhich make it easier for the diver to breathe.
  • a conventional snorkel has only one tube and have the result that the diver breathe in the used airwhich remains in the tube. This cause the result that the diver will be very quikly exhausted and therefore have to take a relative deep brethe to gain the fresh air.
  • the fresh air snorkel can be maked twice as long as the conventional snorkel and the diver need not to breathe deeper to gain the fresh air.
  • an breathetube which is divided in two separate tubes near by or inside.the mouthpiece.
  • One of the tubes conduct the air in to the diver and the other tube conduct the air from the diver.
  • a one-way-valve which opens only while the diver take a inlet breathe an another one-way-valve opens only while the diver breathe out the air.
  • the fresh air snorkel according to the invention described at fig.1 a schematic construction of the fresh air snorkel and fig.2 described an axampel of a construction of a one-way-valve.
  • Fig.1 describe the mouthpiese3 connected to an middel-piece 7, at 4, connected to two separate air tubes, one inlet air-tube 5 and one outlet air-tube 6 where both tubes in their whole length are both constructed closed to each other. Both tubes are approximately of same length.
  • an one-way- valve 1 and 2. These are constructed so that one opens while inlet breathing carries out and the other opens at outlet breathing.
  • Fig.2 showes that the valves are fitted in the tubes free end, but other placeing are possible. For axample the valves can be fitted in the opposite end, at A, 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.
