Abstract (en)

[origin: WO8905195A1] In order to improve a whirl nozzle for atomizing a liquid, which has whirl chamber (86) rising above a whirl chamber bottom (34) and tapering toward a nozzle oulet orifice (14) opposite said bottom, at least one whirl channel (42) laterally offset to a central axis (20) of the whirl chamber (86) and opening into the latter, and a whirl parameter of 1, so as to permit an increase in the whirl input pulse at constant or reduced whirl losses, a displacement element (62) rises above the whirl chamber bottom (34) to prevent the formation of an air core in the region of said floor. Said element is arranged concentrically about the central axis (20) and the external diameter of the section nearer said floor is equal to at least one diameter of the nozzle outlet orifice (14).
