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: Method for detecting fires in railway vehicles. For detecting fires reliably and with a reduced error rate, it is proposed that compartment air in a railway vehicle be sucked in by means of at least two suctioning devices operated separately from one another, each in a monitoring region, that the monitoring parameter of the compartment air sucked in be evaluated in the suctioning devices and that a first control signal be output on detection of a monitoring parameter threshold value in at least one suctioning device.

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.

Abstract: The invention application relates to a valve for pipelines of fire fighting systems, with a supply line (32) for extinguishing fluid loaded by excess pressure, with a drain line (34) for the extinguishing fluid, with locking means (36, 46) arranged between the supply line (32) and the drain line (34), and with an actuating means (38) operating the locking means (36, 46) for setting the locking means (36, 46) in an open position and a closed position, wherein, in the rest state, the locking means (36, 46) are in the closed position and wherein, in the case of a fire, the actuating means (38) adjust the locking means (36, 46) from the closed position into the open position in such a way that extinguishing fluid flows from the supply line (32) into the drain line (34).

Abstract: The invention relates to a stationary fire-fighting system comprising an extinguisher fluid storage, a pipe between the extinguisher fluid storage and at least one extinguisher fog nozzle, and a high-pressure pump generating a high-pressure in the pipe. In order to put the stationary fire-fighting system to an additional use, it is proposed that cleaning means, which are connected to the pipe by a junction, are provided in such a manner that extinguisher fluid, via the junction in the cleaning means, can be utilized for cleaning surfaces, the high-pressure pump generating a pressure of over 40 bar.

Abstract: The invention relates to an apparatus for fire-fighting comprising a fire-extinguishing nozzle (4) connected to an extinguisher fluid supply (3) via a pipe (2) and comprising an alarm device (5) which delivers a warning signal at the beginning of a fire-extinguishing process. In such an apparatus the risk of leaks occurring is reduced and effective alarming of the surroundings at the beginning of the fire-extinguishing process is ensured according to the invention by the fact that the alarm device (5) comprises a pressure-actuatable switching device connected to the pipe (2) which triggers the warning signal in the event of an increase in the pressure prevailing in the pipe (2).

Abstract: A portable fire extinguishing nozzle arrangement has a nozzle head provided with fire extinguishing nozzles that may be connected to a supply pipe. A plurality of fire extinguishing nozzles are mutually spaced apart at the free front side of the nozzle head. When supplied with fire extinguishing fluid, each fire extinguishing nozzle generates a mist of fire extinguishing fluid. The fire extinguishing nozzles may be selectively supplied with fire extinguishing fluid individually and/or in groups through a valve combination.

Abstract: A fire extinguishing device activates fire extinguishing nozzle-heads in multiple locations in response to fire-induced activation of one of the fire extinguishing nozzle-heads. The fire extinguishing nozzle-heads are connected to a supply pipe which conducts a fire extinguishing fluid from a pressure generator. Each nozzle-head includes at least one fire extinguishing nozzle and a fire detection contrivance, which, in the event of a fire, triggers the issue of the extinguishing fluid from the activated fire extinguishing nozzle. Each of the fire extinguishing nozzles-heads further includes at least two connecting channels providing communication between the fire extinguishing nozzles and a supply pipe. Both connecting channels are normally closed by respective shut-off devices while the extinguishing nozzle-heads are in a quiescent state.
