Abstract: A nozzle for generating and distributing water fog through discharge orifices (18), for example for use for extinguishing fires fighting equipment. At least two of the channels converge and collide at a point outside the nozzle, which comprises an attachment (10) for connection with a water conduit. The attachment is provided with a support surface (16; 19) for a nozzle head (12; 21, 24). The nozzle head (12; 21, 24) is provided with at least one support surface (17; 22) cooperating with the support surface (16; 19) of the attachment. The discharge orifices (18) are located at the support surfaces (16, 17, 19, 22) between the head (12, 21; 24) and the attachment (10).
