1. A method for operating a pressure atomizer nozzle having a nozzle body enclosing a chamber for at least one of fluid tubulence and swirl, the body having a nozzle bore connecting the chamber to an outer space and having at least one first feed channel for feeding a liquid to be atomized into the chamber under pressure, the body having at least one further feed channel for feeding one of a portion of the liquid to be atomized or a second liquid to be atomized into the chamber under pressure, the at least one further feed channel being formed to generate a swirl, the method comprising the steps of:

  • in full-load and overload operation, introducing all of a liquid to be atomized through the at least one first feed channel for a swirl-free turbulence flow to the turbulence chamber, so that a highly turbulent flow being produced in the chamber passes into the outer space through the nozzle bore, andin part-load and low-load operation, feeding a first portion of the liquid to be atomized through the at least one first feed channel for turbulent flow into the chamber and a remaining portion through the at least one further feed channel for a flow with a high degree of swirl into the chamber, a total flow produced in the chamber passes into the, wherein a proportion of liquid fed in by the at least one further feed channel being increased as a total mass flow of liquid decreases.
