Abstract

The paint-spraying apparatus exhibits a supply line 7 for coating material, extending from the color changer to the atomizer. Cut-off valves 26, 27 installed in the supply line delimit an insulating section 25 of said supply line, which insulating section is associated with means 28 to 32 for emptying and flushing said insulating section 25. A voltage divider 16 is connected in parallel to said insulating section 25. When colors are changed, the residual coating material present in said voltage divider 16 can be moved into the empty insulating section 25, after which it is forced by means of slugs back through the entire supply line 7 to the color changer 1, and is thus reclaimed.
