Abstract

Improved head of paint spray guns characterized in that a trigger for its actuation located between the handle that presents the compressed air intake and the connection for the front paint reservoir, is related through a bushing, with a long longitudinal cylindrical stem that presents in its front part a conical shutter of the paint duct and in its rear part a slider with a throat and an elastic sealing ring, sliding that can slide along with the shank axially, by the action of the trigger, inside a box with two crowns of parallel openings all against the action of a concentric helical spring and supported on the flange of a threaded stop piece at the rear end of the shank, so that the squeezing of the trigger is to produce the simultaneous unblocking of the paint duct and of the air that passes through the openings of the box and the throat of the slide towards a upper induct of the head that inclines incline towards the front, where it branches into two conduits that open onto a nozzle, single-piece element with a central axial hole for the passage of paint, ending concretely on respective peripheral grooves, a front and rear of the nozzle, joined with the front part thereof in a frusto-conical shape, by a plurality of holes of varied inclination forming, in a chamber defined between the frustoconical tip of the nozzle and a conical nut of conical shape of decreasing section, a current of accelerated and turbulent air that causes the inner drag and spray of the paint when pressing the trigger, forming a homogenous fog for the paint (Machine-translation by Google Translate, not legally binding)
