Abstract

In order to enable nozzle cleaning (17) of the spray gun to be more intensive and not protracted in time, in the same there is provided an atomiser air bore hole (32), into which compressed air is fed from the atomiser air valve (28). The atomiser air bore hole (32) opens out into a mixing chamber (16) of the atomiser nozzle (17). The atomiser air bore hole (32) is connected via a valve (40) to a cleaning agent feed line (41). The valve (40) is actuated via a switching element (44), through which the atomiser air is guided into the atomiser air bore hole (32) upstream of the valve (40) when the control air feed (20) is shut off and thus the paint feed (19) is shut off.
