Abstract: An improved fluid supply head for high speed rotary atomizers in which high velocity low volume air is introduced directly into the spindle shaft and sealing recesses of the head downstream of bearings supporting the shaft and exhausted along the spindle shaft and along the inner periphery of the atomizing disc. This high velocity low volume air, as it emerges at the disc, creates a venturi-like action that draws the spraying fluid towards the center of the disc axis to form an improved doughnut-shaped spray pattern. This high velocity low volume air also fluid seals the bearings.
