Zusammenfassung:	A fire extinguishing apparatus has a fluid storage tank, a fluid supplying system, and a fluid atomizer. The fluid atomizer includes a nozzle (12) equipped with a profiled channel, a cylindrical chamber, and a fluid flow swirler (17). Guiding elements (18) of the swirler (17) are uniformly distributed in an azimuth over a cross section of the cylindrical chamber. The edges of adjacent guiding elements (18) define through apertures in a projection onto a cross section of the cylindrical chamber. A diaphragm (15) is located upstream of the swirler (17) and is provided with apertures (16) arranged opposite the through apertures formed in the swirler (17). The azimuthal movement of the diaphragm (15) relative to an axis of symmetry of the cylindrical chamber changes the mutual arrangement of the apertures (16) of the diaphragm (15) and apertures of the swirler (17). This results in changing of a cone angle of an atomized gas-droplet flow spray.
