Abstract
A centrifugal device for atomizing a coating product comprises a generally bowl-shape rotating member having an inside wall substantially perpendicular to the rotation axis of the rotating member between a drive hub and the interior surface of the bowl. The wall defines within the bowl a front cavity open in the spraying direction and a rear cavity surrounding the hub. A coating product nozzle and a cleaning product nozzle are accommodated in the rear cavity and are both directed towards the wall. Passages are formed at the outside periphery of the wall near the interior surface, and the wall incorporates an annular opening communicating with the rear cavity and within which is defined a reflector surface adapted to reflect some of a jet of liquid towards the central part of the wall. The cleaning product nozzle is oriented towards the reflector surface.
