Between the handle 3 of a spray gun and a compressed-air inlet fitting 19 is a valve body 11 provided with two blind bores 14, 15. The bores communicate via holes 16, 17 in the body and an outer chamber 27 formed in the handle. An adjusting member 8 comprises a locking nut 12 mounted on the valve body 11 and axially movable on the same so as to progressively open or close the air passage through said through holes 16, 17, among which the ones 16 relating to the bore 14 are of differentiated diameters. <IMAGE> |
