Abstract

An atomizer assembly (10) drives an atomizing bell (108) to apply paint onto a part (14). The atomizer assembly (10) includes a core (24) having at least one paint line (26) extending therethrough, a turbine device (40) circumscribing an axis (A) and disposed in the core (24), and a turbine unit (62) surrounding the pain line (26) and having a shaft (104) rotatable relative the turbine device (40) with several turbine blades (130) connected to the shaft (104). A plurality of nozzles (64, 66, 68) are defined in the turbine device (40) and are positioned relative a turbine wheel (106) connected to the shaft (104) to drive fluid, i.e. gas onto the turbine blades (130). An annular wall (94) extends outwardly from one of the terminal ends of the turbine device (40) to define a seat (96) for engaging the core (24) to maintain a fixed gap between the paint line (26) and the shaft (104) and to eliminate contact therebetween.
