The invention relates to a method for modifying the swirl motion of a liquid in the swirl chamber of a nozzle and swirl generator for nozzles. Such nozzles are used especially in industrial burners, oil burners and installations for cleaning flue gas and spray-drying food. Owing to the disadvantages of state-of-the-art technology, the invention aims to provide a method and a corresponding nozzle which make it possible to adjust the mean droplet diameter at a constant volume flow rate or to maintain the droplet spectrum constant in case of adjustment of the volume flow rate. To this and the invention provides for the partial flows (T1, T2) to be distributed across supply channels (4a, 4b, 4c, 4d) which differ in terms of their cross-sections at their point of connection with the swirl chamber (3). When the partial flows (T1, T2) are divided across more than two tangential supply channels (4a, 4b, 4c, 4d) the cross-sections are constituted by the sum of cross-sections of the supply channels (4a, 4c or 4b, 4d) branching off the corresponding partial flow (T1, T2). As a result the sums of the cross-sections at the point of connection (S1, S2) of the partial flows (T1, T2) with the swirl chamber (3) are different.
