Definitions

  • the invention relates to a gas generator for buoyancy bags of watercraft according to the preamble of claim 1.
  • the object of the invention is to propose a rescue system that o. G. Disadvantages not.
  • the invention solves this problem according to the characterizing features of claim 1.
  • the proposed system consists of a plurality of modules, which in turn consist essentially of an inflatable bag and a gas generator. Since the gas generator only has to produce as much gas - because the gas from the bag is held - that the bag is fully inflated in the greatest depth, the gas generator can be significantly smaller than the known from EP 0 736 450 B1 Known. However, this system requires a relatively long blowing time of the gas generator and relatively cold gas (injury of the bag, reduction of the surface by cooling).
  • the gas generator consists of a high and a low pressure chamber, which are connected by a throttle.
  • the high-pressure chamber is the gas-supplied sentence and the ignition.
  • the gas generated in this room then flows through the throttle in the low-pressure space in which next to gas collecting and Gasleit adopteden a - also gas-producing - granules. From this low-pressure space, the cold gas flows through openings in the bag, thereby bursting the packaging system and sets the bag.
  • the o. G. Throttle not only determines the flow rate of the gas but also ensures that the burnup of the set is independent of the external pressure up to a - adjustable - level of the external pressure (corresponds to the water depth), d. H. from the water surface to the design depth, the gas rate and gas quantity delivered by the gas generator is constant.
  • the mentioned gas collecting and Gasleit Anlagenen serve to lead the gas as low loss as possible through the granules that the gas is cooled down to the desired temperature by the resulting reactions.
  • the set 1 is together with the ignition 2 shown here only schematically in a cylindrical high pressure chamber 3.
  • the gas has there about 1000 ° C. So that the part 5 can withstand the strongly erosive gases despite a light construction for a sufficient time, it is lined with a graphite protection 6. From the part 5, the gas enters the tube coil 11, in which a gas-producing granules 8 is located.
  • the low-pressure part 7 must - to ensure the required reactions between gas and granules 8 - be sufficiently long. This length interferes with the application of the gas generator 10. Therefore, the low pressure part 7 was formed as a tube coil 11, which winds around the cylindrical high pressure chamber 3 and the distributor part 5. Used in the distribution part 5 baffles 12 and networks 14, 16 together with arranged at suitable intervals 18 spaces 20 - without granules - for the desired flow guidance, see. Fig. 2. From the tube 50 with the provided by a network 48 outlet cross section, the "cold" gas flows at about 75 ° C.
  • the housing 22 is surrounded by a further housing 23. This has the same height as the housing 22.
  • the housing 23 are provided with rectangular cross-section channels 30-32 in three levels.
  • the channels 30-32 are connected through openings 34 to 36 with each other.
  • Dividers 38-40 respectively close the gas channels 30-32 in the horizontal plane.
  • the gas channels 30-32 form a multi-level cascade. This corresponds to the principle of the coiled tubing 11 according to FIGS. 1 and 2.
