ABSTRACT:
An apparatus for atomizing and dispensing a coating material includes a turbine having a housing and a shaft for rotatably supporting an atomizing device. The shaft includes an outer end extending from the housing for mounting the atomizing device. The shaft outer end includes a tapered portion, and the atomizing device includes a central tapered aperture for receiving the tapered portion of the shaft outer end. The housing is divided into a high-pressure side and a low-pressure side by a nozzle plate which directs the flow of compressed air from the high-pressure side across a driven wheel mounted on the shaft adjacent the nozzle plate. The high-pressure side lies between the atomizing head and the nozzle plate so that compressed air moving through the nozzle plate and the driven wheel to the low-pressure side flows away from the atomizing head. This motor arrangement minimizes parasitic air leakage around the shaft and disturbances to the film of coating material on the atomizing device which could result from such parasitic leakage.
