Abstract
The present invention is directed to a powder paint delivery method and apparatus employing a pressurized reservoir pump that supplies a controlled stream of densely fluidized or dense phase powder paint to the applicator though a powder delivery conduit. The powder flow rate is a function of the pressure in the reservoir and the flow resistance from the reservoir to the applicator, and is therefore very stable over time, and simple to control. The powder flow can be controlled by holding the resistance of the powder flow path constant and varying the pressure in the reservoir, or by holding the reservoir pressure constant and varying the resistance of the powder flow path.
