Abstract

A rotary atomizer for spray coating objects includes an onboard color changer valve manifold as well as an optional onboard fluid pressure regulator. The manifold facilitates rapid and efficient color changing while reducing coating material wastage and solvent usage. The invention also contemplates mounting the color changer repositionally along an axis which preferably coincides with the rotary axis of the atomizer. This facilitates installation and removal of the regulator and permits the coating material flow path between the discharge port of the color changer and the atomizing head to be kept short and straight which improves flow control and facilitates thorough flushing of the flow path with solvent. Other improvements including a particular color changer manifold and atomizer head structure are also disclosed.
