After paint has been fed through one of the lines to the spray nozzle followed by closing of a valve means (,) associated therewith for changing the arrangement (,) supplying paint, a device (,) is adapted to feed such a volume of fluid into this line upstream of the valve means, with respect to the paint feeding direction, in the reverse direction so that the paint present in the line is pushed back into the arrangement without the fluid reaching it.
