<p>The nozzle body and inserting element have opposite faces (22,40), between which the outlet aperture is formed. The inserting element has an outer thread engaging the inner thread (30) of the nozzle body. This enables an axial motion of the inserting element in the direction of the longitudinal axis (48) of the nozzle body to change the gap width of the aperture. Pref. the inner thread lies in an axial through bore (26) of the nozzle body.</p> |
