FILTER DEVICE FOR A FIRE-EXTINGUISHING INSTALLATION

摘要

Fire protection equipment for estinguishing fires in the cargo space of an aircraft includes two containers for extinguishing evaporating liquid; a common conduit system with nozzles distributes the liquid and is directly connected to one of the containers; the other container is also connected to that conduit system but through a series connection of a water adsorption filter, a solid particle filter, a pressure reducing stage, and a throttle to establish a constant flow rate from the second container into the conduit system, a check valve prevents back flow into the latter container.
