Zusammenfassung: | A spray head is provided comprising a driver section and a nozzle section. The driver section has a central hub carrying helical vanes mounted in the bore of a generally tubular housing. The liquid to be atomized enters the housing bore, flows over the hub to form an annular sheet, and is caused by the vanes to rotate helically. The nozzle is connected to the housing at its downstream end. It comprises a generally tubular body whose bore communicates with the housing bore. A circumferential row of axially extending ridge-like members extend into the nozzle bore from the bore surface at the nozzle outlet. Individual portions of the annular sheet of liquid each contact a face of one of the ridge-like members and are deflected to form a sheet of liquid egressing from the nozzle outlet. These latter sheets spread and form spray. |
