Abstract

The color changing valve block (1) selectively couples a number of different paint color lines to a spray gun (Z) via individual valves (F1-Fn), spaced along a common paint line (2) leading to the spray gun, with a rinsing medium valve (V1) and an air feed valve (PL1) at opposite ends of the valve block, for feeding a rinsing medium and pulsed air through the paint line in opposite directions. An Independent claim for rinsing a color changing valve is also included.
