<p>The nozzle (26) has a rotation chamber (37) arranged upstream to a nozzle opening, and a rotation channel (35) tangentially discharging into the rotation chamber, where the rotation channel displaces the liquid in rotation movement that is coaxial to the nozzle opening. The liquid is discharged into the rotation chamber by movement components that are aligned opposite to a nozzle discharging direction. The rotation channel has a cross-section, which reduces from outside to inside in the direction of the rotation chamber.</p> |
