ABSTRACT:
A first wash fluid discharging passage having an outlet end thereof opened to an outer peripheral surface is provided on a rotary atomizing head and positioned behind a paint reservoir. A second wash fluid discharging passage having an outlet end thereof opened to the paint reservoir is also provided on the rotary atomizing head positioned around a fore end of a paint tube. Also, a nozzle is provided at a fore outlet end of a wash fluid tube. The nozzle internally defines an annular chamber for pooling a wash fluid. The nozzle includes first and second outlet openings to spurt a wash fluid toward the first and second wash fluid discharging passages. Further, a check valve in the annular chamber of the nozzle prevents a reverse flow of a wash fluid.
