Abstract

A rotary atomizer is provided with a center feed tube which forms a stationary central shaft. A rotating shaft is fitted over the stationary shaft with ball or air bearings and has a rotationally symmetric turbine wheel thereon. Located at the end of the rotating shaft is a rotary atomizing cup which is fed by the center feed tube. The forward face of the cup terminates in the discharge edge and is fed by a nearly continuous slot which is formed by a distributor located in the center of the cup and which is spaced from the main body of the cup by three small pins. A small portion of paint is allowed to flow through a diffuser located in the center of the distributor and which provides continuous wetting of the front of the distributor so as to prevent the flaking of dried paint.
