Abstract
The present invention relates to a device for cleaning paint distributing channels in spray guns, whereby paint distributing channels are adapted to direct paint from a supply (3) thereof to a paint discharge nozzle (5) and cleanable by leading a dissolvent (6) filled into the paint supply (3) from the supply through the paint distributing channels (2) and out from the spray gun (1) through its paint discharge nozzle (5). In order to prevent the dissolvent (6) flowing through the paint distributing passages from escaping into the surroundings, the device comprises a suction system (7) in which a vacuum is generated and which includes a connecting unit (8) to which the paint discharge nozzle (5) of the spray gun (1) may be connected or which may be connected to the paint discharge nozzle (5) in order to, by means of the vacuum in the suction system (7) suck dissolvent (6) from the paint supply (3) through the paint distributing channels (2) and the paint discharge nozzle (5), whereby one or more collecting containers (9) are provided to collect dissolvent (6) suck from the spray gun (1).
