Abstract

A fire fighting supply system which is self-contained and provides regulated flows of air and water. The air atomizes the water upon passage through a plurality of atomizing nozzles. Atomized water droplets conveyed in a fog or mist provide a more effective fire extinguishing agent.

Claims

1. A fire fighting supply system utilizing pneumatic atomization for extinguishing fires, comprising in combination:

a vehicle having emergency warning devices and storage areas for fire fighting equipment;

a water tank and pump assembly for supplying and pumping water to an aftercooler, and a hose and nozzle assembly;

an air compressor for supplying a pressurized flow of air to the hose and nozzle assembly;

said water operated aftercooler disposed to cool warm compressed air from said air compressor;

manual and automatic ratio flow regulating devices;

said hose and nozzle assembly comprising a live hose reel, a hose, and a nozzle apparatus with a plurality of pneumatic atomizing nozzles.

2. A fire fighting supply system as set forth in claim 1, wherein said system has an auxiliary coupling for an additional hose.

3. A fire fighting supply system as set forth in claim 1, wherein said water tank has a hydrant connection coupling.

4. A fire fighting supply system as set forth in claim 1, wherein said hose is coaxial with centering ring spacers and a reinforced center tube such that the water and air flows are maintained separate until atomization.

5. A fire fighting supply system as set forth in claim 1, wherein said hose is of parallel design such that the water and air flows are maintained separate until atomization.

6. A fire fighting supply system as set forth in claim 1, wherein manual shutoff valves are disposed such that control of air and water flow may be manually maintained to said water tank, water pump, hose reel, and hose and nozzle assembly.

7. A fire fighting supply system as set forth in claim 1, wherein said nozzle assembly has an air breathing mask coupling connected with the air supply.
