Abstract
A dishwasher, dishwasher sprayer, and method of spraying utilize a tubular spray element with multiple selectable spray patterns that can be used during a wash cycle. In some instances, multiple selectable spray patterns may be supported through the use of a multi-walled tubular spray element having concentric wall sections that are movable relative to one another to selectively activate one or more apertures and thereby modify a spray pattern emitted by the tubular spray element. In other instances, multiple selectable spray patterns may be supported through the use of a multi-chamber tubular spray element in which different sets of apertures are in fluid communication with different chambers in the tubular spray element and flow is selectively controlled to one or more of the chambers.
