Patent ID: 7051950

Claim:
A method of delivering paint to a paint atomizer assembly using a robot comprising the steps of: providing a dosing pump within a housing and being disposed between a paint tube and a paint atomizer forming an annular space between the housing and the dosing pump, the paint tube being a wound coil located in the annular space and including a scraper slidably disposed therein, said dosing pump being a direct drive mechanism controllable to convey in two opposite directions, the paint tube being coupled between the dosing pump and a source of a pressurized medium; delivering paint to said assembly; operating said dosing pump in a first direction thereby filling said paint tube and forcing said scraper rearwardly in said paint tube away from said atomizer; pushing said scraper forwardly toward said atomizer with the pressurized medium thereby delivering paint to said dosing pump; and operating said dosing pump in an opposite direction thereby delivering paint to said paint atomizer.
