Abstract
A spray nozzle assembly which can provide any of multiple high-pressure spray patterns is durably and affordably built by disposing the spray-forming apertures on a distinctly formed, hard, flat plate fixed to the end of a rotatable barrel with multiple channels. As the barrel rotates within a coupler sleeve, individual channels are sequentially directed into a liquid flow path established by the coupler. Liquid flowing through a selected channel passes through the aperture in the plate associated with that channel, forming a desired spray pattern. A cap that may be mounted over the plate and a portion of the barrel protects against debris becoming lodged between the plate and the barrel, and may have a separate aperture aligned with a separate channel in the barrel to allow production of a low pressure spray pattern.
