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.

Abstract: The invention relates to a railway vehicle comprising a fire-fighting system having a supply container for extinguishing agent, a system of pipes, means for dispensing extinguishing agent, and a pressure-generating means. To improve the reliability of this system, it is proposed that the pressure-generating means be coupled to a compressed-air supply belonging to the railway vehicle, that a quiescent pressure can be generated in the system of pipes with the help of the pressure-generating means, and that a case of fire can be detected by means of a pressure drop in the system of pipes.

Abstract: For fire-fighting an extinguishing nozzle body 2 for spraying extinguishing fluid and a fire-fighting device are proposed. The extinguishing nozzle body is characterised by at least two spray nozzles 4 arranged along a periphery of the extinguishing nozzle body 2 and at least one deflector 8 arranged in the area of the spray jet 6 of the extinguishing fluid emerging from the spray nozzles 4. Effective fire-fighting is achieved in that a spray angle 10 of the spray jet relative to the lateral surface of the extinguishing nozzle body 2, a angle of attack 12 of the deflector 8 relative to the direction of the spray jet 6, a clearance 14 between the deflector 8 and the lateral surface of the extinguishing nozzle body 2 and a high pressure of the extinguishing fluid is set in such a way that a cone-shaped spray pattern ensues.

Abstract: The invention relates to a method and a fire fighting device, wherein at least one extinguishing fluid container 2 is pressurized with propellant for releasing an extinguishing fog via at least one extinguishing fog nozzle 4, and wherein at least one extinguishing gas nozzle 6 is pressurized with propellant, wherein the pressurization of the extinguishing fluid container 2 and the extinguishing gas nozzle 6 takes place via a joint propellant supply 8. To render possible targeted pressurization with either extinguishing fluid or extinguishing gas, the invention proposes that optionally only the extinguishing fluid container 2 or only the extinguishing gas nozzle 6 is pressurized with propellant via the joint propellant supply 8.

Abstract: Closure device 2 for pressure cylinders 6 storing extinguishing fluid 4, with a pressure cylinder 6 and an adapter piece 8 for the connection of an immersion pipe 10 arranged in the pressure cylinder 6, with a connection piece 12 arranged outside the pressure cylinder 6. In order to guarantee operation of a fire extinguishing device secure against frost, it is proposed that the immersion pipe 10 and the connection piece 12 are formed in such a way that the connection piece 12 in an idle state is partially filled with extinguishing fluid 4, the connection piece 12 comprises a riser pipe 14, in such a way that the riser pipe 14 lies at least partially above the level 16 of the extinguishing fluid 4, and that the riser pipe 14 comprises a bursting disc 18, in such a way that a gas space 20 is formed between the bursting disc 18 and the extinguishing fluid 4.
