The invention relates to a spray head, preferably for extinguishing fire, comprising a frame (1''''), an inlet (2'''') and a passage (7''''a, 7'''') leading to at least one nozzle (6''''a, 6''''b) with an opening (3''''a) including a first boring (4''''a, 4''''b) and a second boring (5''''a, 5''''b), the first boring comprising a first diameter and the second boring a second diameter. In order for the spray head to have a good efficiency and a very simple construction and to be able to deliver medium in the form of mist, the spray head is characterized in that the first boring (4''''a, 4''''b) comprises a diameter that is 0.1 to 0.9 times the diameter of the second boring (5'a, 5'b, 5'c), that the length of the first boring is 0.25 to 15 times the diameter of the first boring, and that the length of the second boring is approximately 0.25 to 15 times the diameter of the second boring.
