Apparatus (Fig. 1) for atomizing and dispensing a coating material includes a turbine (10) having a housing (12) and a shaft (56) rotatably supporting an atomizing device (11). The turbine includes a turbine wheel (88) having a set of vanes (98) against which jets of air are directed from nozzles (80). The wheel (88) has another set of vanes (230) and a nozzle (224) directs a jet of air against these additional vanes (230) to brake the turbine when the coating material delivery rates or the coating material characteristics require braking, to maximize turbine bearing life, minimize wear, or optimize coating material atomization characteristics. <IMAGE> |
