MIXING NOZZLE WITH A DISPLACEABLE FLOW RESTRICTOR AND SPRAYING UNIT

摘要

The invention relates to a mixing nozzle for fluidic media, especially water-air mixtures, comprising a fluid nozzle (2) that opens into the interior of an external nozzle body (29). Said nozzle body comprises, at a distance from the fluid nozzle (2), a zone, which tapers in a longitudinal axial manner and inside of which a flow restrictor (1) is arranged for creating turbulence in the fluidic mixture. The invention also relates to a spraying unit that is supplied with a fluidic medium via a common supply line by means of a single pump. According to the invention, the outlet of the fluid nozzle (2) is configured as a valve seat for the flow restrictor (1) that can be displaced in a longitudinal axial manner by means of a spindle (6, 5).
