Distribution nozzle and method for wetting a predetermined zone using such a nozzle

摘要

Nozzle (1) comprises spray openings (7) arranged about a central axis (M) of a diffusion element (4) so that an angle of the spray jets (8) varies depending on a polar angle measured around the central axis in the operating state. An independent claim is also included for a process for wetting a defined region around the nozzle with a fluid. Preferred Features: The angle of the spray jets varies depending on the distance to the central axis. The spray openings are arranged in concentric circles having predetermined radii at a distance around the central axis. The diffusion element has a concave curved cross-section.
