Abstract: In one structural arrangement the fire fighting nozzle (18) is connected to the compressor (7) of a gas-turbine engine (4). In the second structural arrangement the fire nozzle (18) is connected to a screw compressor (50) connected to a diesel engine (47). Both types of fire extinguishing equipment have the same fire nozzle (18), whose mixing chamber (19) for the generation of a high-speed two-phase dispersive stream (21) of a bubble structure is made in the form of a block of mixers (35) with front and rear partitions (36,37), in between which pipe mixers (38) are located. Each mixer (38) is equipped with a confusor (43) and a diffusor (44). On the outlet from the fire nozzle (18) the high-speed dispersive stream (21) contains droplets of sizes 100-300 ?m. The fire nozzle (18) has a mixing chamber (19), divided by partitions (36, 37) to a water supply chamber (40), air supply chamber (41) and dispersing chamber (39).

Abstract: The present invention relates to a device for generating a gas-droplet stream, wherein the said device includes a gas-dynamic nozzle (1), which is connected to a chamber (2) for mixing gas and liquid and containing a liquid flow dispersion system (3). The chamber (2) is connected to a liquid and gas supply system through a controlled valve, wherein the said valve ensures an early inlet of a gas flow prior to that of the liquid when the device is turned on, and cuts off the liquid supply when the said device is turned off. The valve comprises two closure members (5,6) which interact with the seats provided on the walls of sealed chambers (8,9) and which communicate respectively with liquid and gas supply ducts (10,11). The member (5) is rigidly connected to a rod (7) so as to be brought in contact with the seat in the gas supply chamber (8), while the member (6) is coaxially mounted on the said rod (7) so as to be capable of displacement along the same upon interaction with a stop.
