The object of the invention is to provide for a new spray head which can be used to extinguish both large, violent fires and small fires. This is achieved in that the spray head has at least one nozzle (7) having a relatively large nozzle opening (8) in order to produce a powerful liquid fog jet at a high propellant fluid pressure, and several nozzles having a respective considerably smaller nozzle opening in order to produce a fine liquid fog jet, whereby said at least one nozzle (7) having a relatively large nozzle opening (8) is arranged to be closed by a spindle (9, 11) loaded with a spring (12) in the direction of the fluid pressure at a fluid pressure which can be determined in advance. |
