Abstract (en)
[origin: EP1238710A1] The powder may be introduced through a central pipe (6) with a square-cut end. Additional air (30) passes through a tube or shaft (3) concentrically-surrounding the central pipe. The pipe is surrounded by an air turbine (2) which rotates it and rotates the spray bell (4). The mixture of air and powder passes through a channel (14) between the outer (8) and inner (12) parts of the bell. There is a wide inner channel (21) in the center of the inner part of the bell which accommodates an adjustable conical tip (22).
