Abstract

The spray nozzle is built into a pipe conduit of a fire-fighting installation comprises a housing in which a flow body forming a torsion mixt. chamber is incorporated. The flow body (4) at the end opposite to the nozzle opening (9) is located tightly in a bore (10) of the housing and is provided with a conical part (6) extending towards the nozzle opening. To the conical part connects a cylindrical pin (7), which in the nozzle opening forms a ring gap (15). The housing (3) is provided with one or more tangential and radially inclined holes (14).
