Abstract

The radial spray nozzle is built into a pipe conduit of the fire-fighting unit comprises a housing in which is formed a torsion mixt. chamber constituting a flow body. The flow body (3) is located in a flow housing (6) supported by a cover housing (11), which at the lower end has a cylindrical tube (12) with a cylindrical nozzle aperture (10). The flow housing in common with the cover housing forms an outer torsion mixt. chamber (13) and an annular gap (14) at a distance from the lower end of the tube (12). The cover housing is provided with one or more tangential and radially inclined holes (15) which end in the outer torsion mixt. chamber.
