Method for modifying the swirl motion of a liquid in a swirl chamber of a nozzle and swirl generator for nozzles

摘要

A method for modifying the swirl motion of a liquid in the swirl chamber of a nozzle and swirl generator for nozzles comprising adjustment of 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. The total fluid flow (5a, 5b) is subdivided into partial flows to be distributed across tangential 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 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. As a result the sums of the cross-sections at the point of connection of the partial flows with the swirl chamber (3) differ.
