Summary: | A rotary atomizer turbine (1) designed as a radial turbine for driving a spraying body, in particular of a bell plate, in a rotary atomizer, having a turbine wheel (4) with multiple tur- bine blades (5), a blade duct (6) which contains the turbine blades (5) and is delimited radially at the outside by a duct wall (7), a braking air nozzle (13), a driving air nozzle (8) and an outlet region (9) at the outlet of the driving air noz- zle (8), wherein the outlet region (9) is delimited at the outside by the duct wall (7) of the blade duct (6) and at the inside by the turbine blade (5) respectively passing through it. One aspect of the invention provides that the blade duct (6) is delimited radially at the inside opposite the braking air nozzle by a stationary flow barrier which prevents the braking air from exiting the blade duct (6) toward the inside in the radial direction. By contrast, a further aspect of the invention provides that the outlet region (9) of the individu- al driving air nozzles (8) is a divergent cross-sectional re- gion (9) which widens in the flow direction and rotates with that turbine blade (5) which is passing the driving air nozzle (8). |
