Abstract
The reversible spray tip assembly has a rotatable turret which may be reversed for cleaning and unclogging. The function of a diffuser is performed by a diffusing member which serves to retain the airless spray tip carbide within the rotatable member and which has an arc shaped aperture located off center and parallel to the circumference of the diametrical passage so as to in effect deflect the stream of fluid flowing through the tip sufficiently to prevent spraying of a coherent stream.
