Patent ID: 7350591

Claim:
Device for preventing and extinguishing fires in a closed target area or in closed sections of a divisible target area, having a buffer reservoir in which oxygen-displacing gas is stored under high pressure, at least one supply line system wherein each of said at least one supply line system connects at least one respective extinguishing nozzle with said buffer reservoir by means of a pressure reducing valve, and a controller for controlling said pressure reducing valve in order to introduce the oxygen-displacing gas into said target area gradually as needed, or instantly in the event of fire, wherein one or more inert-rendered levels of reduced oxygen content in comparison to the natural state can be set into said target area, wherein said buffer reservoir is configured as a high-pressure pipe having two opposite head sections and also having a compressive strength of ≧200 bar, whereby each head section of said high-pressure pipe has a connection to the respective supply line system.
