Abstract: A water delivery device that may be used in a water display is described. The device includes an orifice or outlet through which water is shot out. The shape and configuration of the water device may be varied to dynamically adjust the configuration of the water shot out from the device. For example, the water delivery device may shoot out water in the shape of a fan, and the width of the fan may be varied.

Abstract: An impingement fan water display that may be used in a water display is described. The device may include two nozzles that project streams of water towards each other in an intersecting trajectory and impinge upon each other. The angle of orientation of the nozzles in relation to each other may be varied to produce varying water stream fan widths and shapes. A plate may be located at or near the point of impingement.

Abstract: A decorative water display provides a laminar water bell. A gas burner may be provided inside the laminar water bell to produce a decorative flame. A laminar nozzle having an outlet arranged to eject a laminar jet of water upwardly in a substantially vertical direction may strike an impactor suspended directly above the outlet of the laminar nozzle such that the laminar jet of water forms the laminar water bell. Alternatively, a vertical pipe may supply water to a thin annular region between two plates such that water flowing between the two plates assumes a generally laminar flow characteristic and forms the laminar water bell when ejected from between the two plates. Alternatively, a hemispherical nozzle may have a slot arranged to eject a sheet of water upwardly to form a segment of the laminar water bell.

Abstract: The present invention relates to a decorative water display having many degrees of freedom. The water display has one or more water display nozzles mounted so that the direction of the nozzle may be controlled such as by a computer. In the preferred embodiment, the pressure of the water delivered to the nozzle may also be controlled as desired. Also controllable with the nozzle direction is appropriate lighting to illuminate the discharge from the nozzle for night time use. The elevation of the entire assembly is controllable, preferably between an operative position, a withdrawn position totally below the water surface and a service position extending above the water surface. Various embodiments and features are disclosed.
