A water fountain apparatus including a body including a wall, a top end, a bottom end is disclosed. The wall has an interior surface defining a bore and the bore extends from an opening in the top end to an opening in the bottom end. The bore includes a first portion proximate the top end and a second portion proximate the bottom end. The second portion of the bore is of a greater diameter than the first portion of the bore. The water fountain apparatus may further include a filter mechanism provided within the bore, an engaging mechanism operably engaged with the bottom end of the body, a cover operably engaged with the body, and a valve mechanism that is located in the bore.

The invention is the complex technical solution covering the method for the continuous liquid jet formation and ejection, the generator for ejection such jet and the special shutter for blocking the jet in the generator and designed for use in the method. A distinctive feature is the switching between the two jets, which causes neither a stop of the liquid flow in the generator nor fluctuations in the liquid pressure in it, when one jet is drained to the source of liquid. The invention is intended for organizing the process of metered ejection of free continuous liquid jets, for example, liquid chemical treatment agents, without loss of liquid outside its trajectory.

A spray actuator for use in controlling the flow of a pressurized fluid from a spray can where the actuator includes a body having a top, a shroud having a bottom perimeter and a central passageway oriented parallel to the shroud and a mouth inlet having a cross-sectional area that is smaller a cross sectional area of the slotted outlet wherein a choke point is located in the central passageway.

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.

A gas and liquid knife and a control method thereof are provided. The gas and liquid knife includes a chamber and a knife head. An ejection opening is provided at the knife head The knife head has a first knife lip and a second knife lip. The ejection opening is defined between a first inner wall of the first knife lip and a second inner wall of the second knife lip. The chamber is defined between the first wall plate and the second wall plate slidably connected with each other. The first knife lip connects to the first wall plate. The second knife lip connects to the second wall plate. The first knife lip and second knife lip moves relatively as the first wall plate and the second wall plate slides relatively, such that a minimum distance between the first inner wall and the second inner wall could be changed.

A dosing unit includes a fluid injector having a valve seat; a valve needle movable within the fluid injector between a closed position in which an end engages with the valve seat to block a flow of fluid from exiting the fluid injector and an open position in which the end is spaced apart from the valve seat so as to allow fluid to exit the fluid injector. The valve body, the valve seat and the valve needle form an outwardly opening valve assembly. A pole piece fixedly is disposed within the valve body, and an armature is coupled to the valve needle upstream of the pole piece. A coil is disposed around the pole piece and the armature so as to generate a force when energized to move the armature toward the pole piece and to cause the valve needle to move from the closed to the open position.

A power spout device includes a generally hollow main body having an outlet opening and an inlet opening for engaging the downspout outlet of a horizontal gutter. An elongated paddle is positioned within the main body and is mechanically connected to an electric motor. A fluid sensor is also positioned within the main body and is electrically connected to the motor. The fluid sensor functioning to selectively operate the motor upon detecting the presence of rainwater from the downspout outlet. A controller having a wireless communication unit is positioned along the main body. The controller functioning to receive operating instructions from a remote-control device. An adjustable nozzle is positioned along the output opening to adjust the vertical angle of the water being discharged out of the outlet opening.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

A spraying system for an agricultural sprayer includes a plurality of nozzle assemblies configured for positioning along a sprayer boom. Each of the plurality of nozzle assemblies is in communication at least one boom tubes. A nozzle controller is in communication with the plurality of nozzle assemblies, and the nozzle controller is configured to control one or more of the nozzle assemblies of the plurality to provide a targeted application of agricultural product.

A sprayer system for spraying water, onto and for absorption by, a surrounding area, such as used in wastewater treatment. The sprayer system includes a substantially vertical tubular housing extending from a well base to a distal end from which water communicated to the sprayer system is discharged. The tubular housing includes an inner tubular casing slidably supporting a piston assembly which is movable from the well base to the distal end in response to water communicated from a source to the well base. The piston assembly includes a primary check valve that is biased into engagement with an associated seat and includes a spray nozzle located downstream of the main check valve. When water from the source is applied to an effective pressure area on the piston assembly, an upwardly directed force is applied to the piston assembly when water is delivered to the well base. At least one bypass passage communicates bypass water to a region defined between the piston housing and an inside wall of the tubular casing so that warming water is delivered from the well base and flows around the outside surface of the piston assembly, whereby icing, which would otherwise block movement of the piston assembly, is inhibited.
