Patent ID: 8590631

Claim:
A railway vehicle fire-fighting system, comprising: a supply container for an extinguishing agent; a system of pipes connecting the supply container with means for dispensing the extinguishing agent; a means for maintaining a constant quiescent pressure in the system of pipes, wherein the means for maintaining the constant quiescent pressure is coupled to a compressed-air supply belonging to the railway vehicle, the means for maintaining the constant quiescent pressure filling the system of pipes with gas at the quiescent pressure, whereby in a case of fire the gas filling the pipes escapes the pipes such that the fire is detected by a pressure drop of the gas filling the pipes and the compressed-air supply drives the extinguishing agent by air pressure out of the supply container, into the system of pipes, and out of the means for dispensing; and a fire alarm coupled to the system such that detection of a fire allows the compressed air from the compressed-air supply to be driven into the supply container whereby the extinguishing agent flows out of the supply container, into the system of pipes, and out of the means for dispensing.
