  • the unit had a U-shaped tank with a screwed outlet nozzle on one of the two leg ends.
  • the outflow direction of the active ingredient from the nozzle took place in leg longitudinal axis direction.
  • At the other U-leg end was bolted to a replaceable gas production tank.
  • This U-leg was only partially filled with active fluid so that until Leg end a free space remained. The liquid was towards the free space with an elastic Ball or other analogously acting elements closed.
  • US-A 5,660,236 a device for fire fighting is described.
  • This device had a filled with a drug (3) or fillable storage tank.

  • a dense water mist is ejected under high pressure within a few fractions of a second, which consists of the smallest water droplets (aerosol).
  • This water mist spreads very quickly in the burning engine or cargo space and extinguishes the fire on the one hand by oxygen deprivation (asphyxiation) and on the other hand by cooling the source of the fire.
  • the fine water droplets form a very large surface and thus remove the fire a lot of heat energy, which cools the fire quickly.
  • One liter of water produces about 1.5 m 3 of water vapor.
  • the nebulizer nozzles need not be directed directly to the fire.
