Abstract

Fire protection device for gangways 3 between the coaches 2 of rail vehicles with a gangway 3 between coaches 2 of a rail vehicle, and a fluid-fed fire-fighting device. Effective fire-fighting with low weight is made due to the fact the fire-fighting device comprises a fluid mist nozzle 4 which delivers a fluid mist, whereby the at least one fluid mist nozzle 4 is arranged in such a way that the fluid mist is sprayed into the gangway 3.

Claims

1-15. -15. (canceled)

16. A fire protection device arranged for a gangway between coaches of rail vehicles comprising:

a fire extinguishing fluid fed fire-fighting device,

wherein the fire-fighting device comprises at least one fluid mist nozzle for delivering a fluid mist,

wherein the fluid mist nozzle is arranged within the coach in proximity to the gangway,

the at least one fluid mist nozzle is arranged in such a way that the fluid mist is sprayed into the gangway, so that more than 20-90% of fluid drops of the fluid mist reach the gangway,

wherein the extinguishing fluid is sprayed at a pressure between 5 and 200 bar.

17. The fire protection device of claim 16, wherein a spray direction of the fluid mist nozzle is arranged from the coach into the direction of the gangway.

18. The fire protection device of claim 16, wherein a further fluid mist nozzle is arranged in the gangway.

19. The fire protection device of claim 18, wherein the fluid mist nozzle is arranged in at least one of:

A) the floor area of the gangway, or

B) the side walls of the gangway, or

C) in a roof area of the gangway.

20. The fire protection device of claim 16, wherein the fire-fighting device comprises a central fluid storage.

21. The fire protection device of claim 20, wherein the fire-fighting device comprises fire detection means assigned to the gangway, for the detection of a fire in the gangway.

22. The fire protection device of claim 20, wherein the fire-fighting device comprises at least one section valve connecting the fluid mist nozzle to the central fluid storage.

23. The fire protection device of claim 22, characterized in that, in the event of activation, the fire detection means actuate the section valve in such a way that the section value opens.

24. The fire protection device of claim 16, wherein the fire-fighting device comprises a local fluid storage, in such a way that a fluid storage is provided for each gangway.

25. The fire protection device according of claim 24, wherein the local fluid storage is arranged in at least one of

A) the floor of the gangway, or

B) the roof area of the gangway.

26. The fire protection device of claim 16, wherein the fire-fighting device comprises a pressure pump conducting the fluid to the fluid mist nozzle.

27. The fire protection device of claim 16, wherein the fire-fighting device comprises a high-pressure fluid storage.
