ABSTRACT:
A plural component airless spray gun for mixing and dispensing coreactive liquid materials has a mixing chamber into which coreactive components are introduced and mixed, an airless tip at a forward end of the chamber and from which the mixed components are emitted in a fan-shaped spray, and a mechanical purging rod that is actuable to clean residual mixed components from both the mixing chamber and the airless tip. The purging rod which has a main body of a diameter slightly less than that of the mixing chamber, and a forward end that defines a probe of a diameter that is slightly less than the dimension of the minor axis of an elongate orifice of the airless tip. During spraying, the purging rod is retracted rearwardly of the mixing chamber and of coreactive fluid inlets to the chamber. Upon completion of spraying or periodically as desired, the purging rod is moved forwardly through the mixing chamber until the probe at the forward end of the purging rod extends through the airless tip orifice, to clean both the mixing chamber and the orifice of residual reactive components.
