ABSTRACT:
An airless spray gun reversible spray nozzle unit is provided adapted to replace the normal or standard fixed spray position unit without any modification of the external spray head. The external spray head normally positions and holds the fixed position spray nozzle unit in spray position in the airless spray gun. The present adaptation is made possible by means of a floating or sliding female ferrule axially movably positioned and slideable intermediately between a pair of spaced apart keyed flanges defining the unit size which act as stops therefor and assures a leak-proof machined fit of the reversible nozzle when the inventive spray nozzle unit is positioned to spray, or in reversed position so the orifice of the nozzle can be backwashed and freed of binding occlusions.
The size, weight and form of the unit adds substantially no increase in weight or volume to the conventional fixed position airless spray head spray nozzle unit and is easily and quickly manually reversed when desired.
