Publication number: 20210276027Abstract: The disclosure relates to a rotary atomizer for applying a spray jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that the construction dimensions of the rotary atomizer are coordinated in such a way that the air pressure at the outlet opening of the paint nozzle during operation is lower than the air pressure in the nozzle chamber of the bell cup and in the external rinsing channels in order to prevent a backflow of the coating agent from the outlet opening of the paint nozzle backwards in the direction of the nozzle chamber due to the pressure difference.Type: ApplicationFiled: November 5, 2019Publication date: September 9, 2021Inventors: Hans-Jürgen Nolte, Andreas Fischer
