    • System for washing airbrushes, comprising a pipe (19, 20) for feeding a pressurized detergent liquid to a dispensing nozzle (8, 13) adapted to be placed in fluid communication with the internal duct of the paint channel of an airbrush (6, 7).
      Said system being provided immediately upstream of the dispensing nozzle (8, 13) with a first valve holder fitting (9, 11) placed as derivation with respect to a second valve holder fitting (10, 12); the first fitting (9, 11) being dedicated to feeding with detergent liquid coming from the pipe (19, 20) to the dispensing noozle (8, 13), the second (10, 12) being dedicated to feeding the dispensing noozle (8 , 13) with compressed air coming from a pipe (22, 23) at a pressure higher than that of the detergent liquid.
      It being provided that inside the fitting (9, 11) for feeding detergent liquid there is a shutter (9') with a non-return function when compressed air reaches the dispensing nozzle (8, 13) through the fitting (10, 12) and, inside the fitting (10, 12) for the compressed air supply, a shutter (10') is placed with a non-return function when detergent liquid arrives through the fitting (9, 11) from pipe (19, 20) and the flow of compressed air is interrupted.
      Means being also provided for generating pulses of compressed air upstream of said pipe (22, 23).
