Abstract: A spray nozzle for use in an airless spray gun wherein the surface finish of the spray nozzle tip is highly polished to create a mirror-like or micro-finish, in the immediate area surrounding the exit orifice of the spray nozzle tip, such that during the use of the spray nozzle, the material sprayed therethrough will not substantially build up or collect on the spray nozzle tip in such a degree that would necessitate the removal for cleaning of the tip, thereby significantly enhancing the performance and operation of the spray nozzle in connection with its spraying operations.

Abstract: A spray head which is characterized by a tubular body with an axial bore divided into axially spaced sections of different diameter with the forward section, which is at the discharge end of the head, being of the largest diameter and constituting a chamber in which a spherical spray tip holder is mounted so as to be rotatably seated on the mating inner face of a removably mounted end cap, which holder has a radial socket aligned with a cross bore in the body for receiving a turning member enabling rotation of the tip holder between an operative position for direction of spray material through a discharge aperture in the end cap and a cleaning position for reverse flow of material through the spray tip and a bearing and sealing assembly engaging the tip holder surface opposite its engagement with the end cap which assembly is arranged to minimize the pressure exerted on the tip holder by the spray material and possibly leakage of the product into the tip holder chambers, the latter being provided with a relie
