(57) 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).
