Abstract: The invention relates to a nozzle for spraying liquid, especially water in a snow production cannon. The nozzle consists of a cylindrical body 1 and a cap nut 2 having an axial spraying hole 5 connected from inside by means of an inlet cone 6 to a vortex chamber 7. Between the body 1 and the nut 2 a swirl insert 4 is mounted. The insert divides a fluid supply channel 9 having a partition wall 8 with at least two vortex channels 10. The swirl insert 4 has a flange 11 which fixes the insert axially between the nut 2 and the body 1 through a front 12 and a rare 13 scaling rings, and both of said rings have circular cross-sections. The front sealing ring 12 is mounted in a rectangular groove made on the face of the swirl insert 4 tangent to the face of the nut 2. The rear sealing ring 13 is mounted in a semicircular socket IS made at the inner corner of the rear surface of the flange 11.
