Abstract
A rotatable nozzle assembly for sprayers having a fluid reservoir and spray head wherein the nozzle assembly includes a spray control barrel which receives liquid from the reservoir and which includes a number of annular spaced orifices. The barrel is rotatably mounted in eccentric relationship within a tube portion of the spray head which is closed by a cap having a discharge opening therein so that the orifices in the barrel may be selectively aligned with the discharge opening in the cap to thereby vary the spray pattern discharging from the sprayer.
