초록 ▼

A whirl nozzle for atomizing a liquid has a whirl chamber rising above a whirl chamber bottom and tapering toward a nozzle outlet orifice opposite the bottom, at least one whirl channel laterally offset to a central axis of the whirl chamber and opening into the latter, and a whirl parameter of greater than 1, so as to permit an increase in the whirl input pulse at constant or reduced whirl losses. A displacement element rises above the whirl chamber bottom to prevent the formation of an air core in the region of the floor. The element is arranged concentrically about the central axis and the external diameter of the section nearer the floor is equal to at least one diameter of the nozzle outlet orifice. In one embodiment, the conical seating surface has a smaller apex angle than a section of the whirl chamber wall adjoining the nozzle outlet orifice. In another embodiment, the displacement element is provided with at least one eccentrically arranged reflux bore.
