Definitions

  • the invention relates to an extinguishing system, in particular for mobile devices.
  • the invention has for its object to an extinguishing system create that avoids the risk of damage to the membrane.
  • the extinguishing system according to the invention is characterized by the features of claim 1.
  • the membrane follows the change in volume of the compressed gas cushion - in any position and with the usual accelerations - and also prevents the undesirable effect of re-blowing with compressed gas cylinders.
  • the propellant gas escapes without extinguishing agent to an injector effect at the extinguishing nozzle. This can light up an almost deleted one Cause fire.
  • Further advantages of the invention are that the print medium and the extinguishing agent are separated. Especially if water is used as the extinguishing agent, the reagents be added to improve the To achieve extinguishing ability.
  • pyrotechnic compressed gas generators which only apply the propellant gas pressure when the fire extinguisher should be activated.
  • the compressed gas generator contains a charge with an electrical igniter. At Ignition results from the combustion of a gaseous pressure mixture that is in one pressure-free medium distributed in the pressure reservoir and this pressurizes.
  • an inert gas e.g. Nitrogen can be used.
  • the great Advantage of the invention is therefore to be seen in the fact that the pyrolysis product
  • the compressed gas generator is not mixed with the extinguishing fluid, so that the pyrolysis product does not get into the passenger compartment and thus affects the driver.
  • pressurized gas containers in vehicles at risk of accidents, especially racing cars, to transport it suggests designing a safe system that The standby state is depressurized and in the event of a crash does not produce a vascular crack.
  • the extinguishing agent containers are usually placed where the passenger seat is located.
  • Water is used as an extinguishing agent, which after activation of the Extinguishing system via mist nozzles, then there is optimal fire protection guaranteed. Not only can the fire in the passenger compartment be extinguished with water mist, but also achieve a high level of personal protection because the suffocating effect of the Inert gas is no longer present.
  • the membrane is U-shaped to the valve pointing opening and the open edge of the membrane is on attached to the inside of the extinguishing agent container.
  • the extinguishing agent container consists of an upper and a lower part, which are interconnected.
  • the u-shaped membrane can be attached, for example, to the junction of the upper and lower part his.
  • the extinguishing agent container 1 consists of an upper part 10 and a lower part 11 which are interconnected.
  • a weld seam 15 intended. Instead of the weld seam, a screw connection, a Adhesive connection or the like may be provided.
  • a nozzle 6 is provided with a valve 5 as a blocking element.
  • a rupture disk 22 can also be provided (FIG. 5).
  • the lower edge of the top 10 has an inward thickening 12 with an outer recess 13.
  • the upper edge of the lower part 11 comprises the recess 13.
  • the one facing inwards Thickening 12 is provided with a recess 14 into which the thickened part 15 one Membrane 3 is inserted. In this way it is provided with a thickening 16 Membrane 3 attached within the extinguishing agent container 1 and thus forms an upper one Fluid space 2 for a pressureless fluid and a lower pressure reservoir 4 for one Print medium.
  • the membrane 3 can also be fastened by means of a bead 25 and a clamping ring 26 can be made (Fig. 2).
  • a filler neck 7 with a filler element 8 for filling the pressure medium 4a intended.
  • a pressureless inert gas 4b can also be used be used.
  • a Compressed gas generator 19 set in motion, which is connected to the connector 7 via a line 18 connected is.
  • an ignition device 20 is activated by one Control 21 ignited.
  • the medium in the compressed gas generator is generated by combustion a compressed gas that mixes with the unpressurized inert gas 4b and so that when the volume increases, the pressure on the membrane 3 on the Extinguishing fluid in the fluid space 2 transfers.
  • the Bursting disk 22 destroyed so that the extinguishing fluid via opening 17, line 23 and one Fog nozzle 24 is directed to the source of the fire in the racing car.
  • a Valve 5 is opened via a control device.
  • Fig. 1 also shows the membrane 3 in dash-dotted lines Representation according to which the extinguishing fluid is discharged.
  • the thickening 16 counters the opening 17 and closes it.
