Patent ID: 8881672

Claim:
Atomisation system for a rotary atomiser for the application of a coating agent, comprising: a rotatably mounted bell cup having an annular circumferential spray edge with a predetermined external diameter, the bell cup being configured to atomize the coating agent and discharge a spray jet of the coating agent, a shaping air ring having a first shaping air nozzle annulus with a first plurality of shaping air nozzles arranged in an annularly distributed manner and a second shaping air nozzle annulus with a plurality of shaping air nozzles arranged in an annularly distributed manner, the shaping air ring being configured to discharge a first shaping air and a second shaping air for shaping the spray jet discharged by the bell cup such that the first shaping air and the second shaping air are each directed onto the spray edge of the bell cup, wherein the two shaping airs have separate shaping air inlets and are adjustable independently of one another, wherein the shaping air nozzles of the first shaping air nozzle annulus are oriented axially and axially discharge the first shaping air, the shaping air nozzles of the second shaping air nozzle annulus are twisted shaping air nozzles oriented in the circumferential direction against the direction of rotation of the bell cup and discharge the second shaping air with a predetermined angle of twist in the circumferential direction, and the twisted shaping air nozzles have a smaller nozzle diameter than the axially oriented shaping air nozzles.
