Abstract
In an atomizer wheel for the atomization of liquids by ejection through a number of orifices in the side wall of the wheel, whipping-in of air into the atomized liquid is reduced by provision of a protrusion around the leading edge of each orifice relative to the direction of rotation, whereby the liquid flowing backwards relative to the side wall is guided outside the leading edge of the orifice to a liquid inlet passage at the rear part of the ejection orifice relative to the direction of rotation. The protrusion may be formed by a bushing inserted in the ejection orifice and projecting inwardly from the side wall, at the rear side of which relative to the direction of rotation the inlet passage is formed as a slit.
