Abstract:

There is disclosed a spray head for an airless spray gun. The spray head has a tubular housing for removable attachment to the discharge end of an otherwise conventional airless spray gun, adjacent the valve member of the spray gun. The housing is counterbored to form an inner annular shoulder and contains a removable plug that is slidably received within the housing. The annular shoulder is stop for the plug which is retained in the housing at the preselected location by a retainer member that is removably threaded into the discharge end of the housing. The plug has, on its upstream end, a valve seat to engage the valve member of the spray gun and, on its downstream end, a discharge orifice formed by divergent angular bores which intersect a through bore of the plug. Preferably the plug also supports, on its downstream face, a diffuser baffle that extends transversely across and slightly axially spaced from the discharge face of the orifice which is supported by a pair of diametrically located, axial prongs that support the baffle.
