  • the rotation chamber has inlet openings through which the feed channels open into the rotation chamber.
  • the feed channels are arranged tangentially to the cross section of the rotation chamber and open tangentially into this. In particular, the feed channels run in a projection onto the plane of the cross section of the rotation chamber tangential to the cross section of the rotation chamber.

  • the tapering side walls result in a guidance of the rotating liquid column in the direction of the nozzle opening.
