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.
In a spray head for producing a mist, the improvements comprising a frame, an inlet and a main channel leading from the inlet to at least one nozzle with an opening including a first boring and a second boring, the first boring comprising a first diameter and the second boring comprising a second diameter, wherein the first diameter is 0.1 to 0.9 times the second diameter, the length of the first boring is 0.25 to 15 times the first diameter, and the length of the second boring is approximately 1 to 15 times the second diameter, wherein the first boring is at least substantially aligned with the second boring and the borings are at an angle in relation to the main channel.
