DISPOSITIVO ATOMIZZATORE ROTATIVO PER RIVESTIMENTO O VERNICIATURA DI MANUFATTI

A coating applicator having a high speed rotary atomizer bell, 12, driven by an air turbine, 23, has a governor 28, which controls the speed of the air turbine to provide more uniform atomization throughout a wide range of loads on the atomizer. Compressed air flows through passages 19, 20, 21, the...

Zusammenfassung:A coating applicator having a high speed rotary atomizer bell, 12, driven by an air turbine, 23, has a governor 28, which controls the speed of the air turbine to provide more uniform atomization throughout a wide range of loads on the atomizer. Compressed air flows through passages 19, 20, 21, the turbine wheel, 23, and, through openings 24 in the turbine wheel to exhaust ports 25. The passages from chamber 20 to the turbine are blocked when the turbine rotation is too fast, by pressure actuated piston governor, 29, operated by centrifugal vent valve 41, 45.
