Abstract

The conical nozzle has a nozzle component (10) with a swirl chamber (18), a feed bore (22) in one wall of the swirl chamber, and an outlet bore (20) in a first end wall of the swirl chamber. An axially symmetrical protrusion (30) or recess is provided on a second end wall of the swirl chamber, and at least two blind holes (32) are located in the first end wall adjacent to the outlet bore. An encompassing annular chamber in communication with the feed bore and nozzle component is provided in the region of the feed bore.
