Abstract
The present invention provides a nozzle assembly for producing varying water patterns. In one embodiment, a variable first flow of water is constrained to flow in a linear direction. A variable second flow of water is applied to the first flow of water to impart a twist to the first flow of water. The resulting flow of water has a height component that is largely determined by the first flow of water and a lateral component that is largely determined by the second flow of water. For example, if there is only a first flow and no second flow, the resulting water effect is a narrow column of water. If there is no first flow and a second flow, the resulting water effect is a cone with a small vertical dimension. If there are both first and second flows, a cone is produced with a vertical dimension that is largely determined by the first flow and a lateral dimension that is largely determined by the second flow.
