Abstract
A reversible airless nozzle for a spray gun comprises an adapter mounted on a forward end of the gun, a filter in the adapter and an airless spray tip captured between the adapter and a safety cap. Should a small outlet orifice from the spray tip become plugged, it may be cleared by inserting the spray tip into the forward end of the adapter in the direction reverse to that for normal spraying, and then briefly triggering the spray gun to eject the blockage. The spray tip is carried in a housing adapted for a snug fit into the forward end of the adapter during cleaning, and an insert in the housing prevents the spray tip from being forced from the housing when reverse hydraulic pressures are applied.
