Abstract

A rotary atomizer turbine is provided, the turbine including a turbine wheel with multiple turbine blades, a blade duct containing the turbine blades and being delimited radially by a duct wall, a braking air nozzle, a driving air nozzle and an outlet region at the outlet of the driving air nozzle. The outlet region is delimited at the outside by the duct wall of the blade duct and at the inside by the turbine blade respectively passing through it. The blade duct is delimited radially at the inside opposite the braking air nozzle by a stationary flow barrier. Furthermore, the outlet region of the individual driving air nozzles is a divergent cross-sectional region which widens in the flow direction and rotates with that turbine blade passing the driving air nozzle.
