A water nozzle with a flow head is provided with at least two separate water supply devices that supply, in a controllable fashion, different water volume flows to the flow head. The flow head generates an annular jet from the different water volume flows. By controlling the water volume flows, alternatively a slim annular jet or a widened annular jet is generated by the flow head. A deflection element with a central outlet opening is provided, wherein the central outlet opening is arranged in a flow direction of the annular jet downstream of and spaced apart from the flow head. A deflection device surrounds the central outlet opening. A diameter of the central outlet opening is designed such that the slim annular jet is able to pass through the central outlet opening while the widened annular jet impacts on the deflection device surrounding the central outlet opening.

A water discharge device comprising a water discharge member formed with a slit-like discharge port and a discharge path, wherein the discharge path is formed with a reservoir chamber for holding, as reserve water, water flowing into the discharge path from its upstream side, and is formed with a constricting flow path that sends forth the reserve water in the reservoir chamber to the discharge port, and lateral surfaces on either side of the discharge path in its width direction are formed such that a path width of the discharge path spreads as approaching its discharge port side from its reservoir chamber side, and is formed such that the angle formed by an imaginary line paralleling the width direction of the discharge port and, on the lateral surfaces, a tangent line passing over the discharge port's opening rim is greater than or equal to 45 and less than 90.

A low profile, lighted waterfall apparatus for producing a sufficiently lit artificial waterfall having a light source chamber, distal to a waterfall slot/primary outlet and substantially aligned on the same plane therewith, and a port for accessing the light source, such that the light source can be easily accessed, inserted, removed, and/or replaced. The light source chamber having a transparent, semi-transparent, or translucent divider to shine light towards and across the waterfall slot/primary opening via a grooved spreading manifold/area/passage. The grooved spreading manifold/area/passage configured to spread the flowing water, and direct the water as a fluid wave guide towards the waterfall slot/primary outlet.

Nozzle orifice shapes and configurations associated with regulating and directing a flowing body of water over a water attraction riding surface for performing board-riding maneuvers is described. The nozzle orifice shapes and configurations according to the present invention includes shapes and configurations allowing for a flow of water over a ride surface which may include complex shapes which do not lend themselves to use with existing nozzle technologies. The present invention also includes nozzle arrays which may be made up of two or more nozzles arranged substantially adjacent or within close proximity to one another to create beneficial flow characteristics for performing board riding maneuvers on a complexly shaped riding surface.

A fountain is provided. The fountain includes: a drape; a catch basin located below the drape and oriented to catch a fluid flowing at least one of over and through the drape; a conduit fluidly connected to the catch basin forming a circuit to return the fluid in the catch basin to flow at least one of over and through the drape; a pump fluidly connected to the circuit and configured to pump the fluid through the conduit; and at least one of the drape, catch basin, conduit includes surface oriented to contact the fluid and the surface includes at least one of copper and silver.

There is disclosed an apparatus for producing a water maze from walls of falling water droplets. The apparatus may comprise a plurality of tubular spray bars each perforated with a water inlet for receiving pressurized water. A series of output holes may extend along a length of each spray bar through which the received water is discharged to produce the droplets. A plurality of connectors may be configured to join two or more of the spray bars at one or more vertices in an array producing the water maze. A flow regulator may be disposed between the water inlet and the series of outlet holes for resistively spreading the inlet water evenly across the length of the spray bar prior to the discharging. A 3D printing of the connectors may facilitate a wide variety of horizontal angles required between spray bars joining at the vertices in one-of-a-kind maze designs.

A weeping wall has a wall body, a flowable substance inlet, at least one mobile deflector, and a flowable substance outlet. The wall body has a flow surface with a magnetic material layer extending along at least a portion thereof. The flowable substance inlet is at an upper end of the flow surface, with a flowable substance continuously flowing therefrom and downwardly onto the flow surface. The mobile deflector is movably engaged to the flow surface and projects therefrom. The mobile deflector includes a magnet and is magnetically held in place on the flow surface to be selectively movable relative to the flow surface to modify a flow path of the flowable substance on the flow surface. The flowable substance outlet is defined at a lower end of the flow surface with the flowable substance flowing continuously therein after running down onto the flow surface.
