A showerhead includes a water outlet and a deflector in axial spaced relation to the water outlet. Water discharged from the water outlet is configured to extend axially through a vertical opening and impact the deflector to form a sheet-like water layer.

A linear oscillating water jet is capable of spraying in a linear oscillating fashion without deviating from a consistent linear path such that a resulting linear spray does not extend beyond a targeted area. Through the use of an internal turbine, energy from an incoming pressurized liquid is used to create rotational motion, which is subsequently converted into an oscillatory, back and forth linear motion by way of a rocker assembly that connects a nozzle assembly to the internal turbine. The oscillatory, linear motion of the rocker assembly is translated into a linear, back and forth rocking motion for the nozzle assembly.

An additive manufacturing nozzles includes a header (41) extending in a width direction of the chamber and which is configured to be supplied with inert gas from the outside, and a nozzle body (43) connecting with the header (41) in the width direction and is configured to horizontally blow out the inert gas, which is supplied from the header, to a molding area. The nozzle body has a honeycomb part (52) which defines an inside of the nozzle body into flow channels through which the inert gas flows, a blowout part (55) disposed downstream of the honeycomb part and which is connected with the honeycomb part in the width direction. The inert gas passed through the plurality of flow channels is led from the honeycomb part to the blowout part, and a porous part (54), which has openings, is disposed between the honeycomb part and the blowout part.

Provided is a nozzle structure, a blow device, and a manufacturing method for parts, a bearing, a linear motion device, a steering device, a vehicle, and a mechanical device which can uniformly and satisfactorily perform various processes with fluid over a wide range on a processing target member. The nozzle structure includes an inner member, an outer member surrounding the inner member, and a laminar flow path formed between an outer surface of the inner member and an inner surface of the outer member to allow fluid to flow. The blow device or the mechanical device having the nozzle structure can process the inner member by flowing the fluid in the flow path.

A liquid flow device to receive fluid and laminarize the fluid flow. The liquid flow device includes a jet nozzle assembly to receive the fluid and direct the fluid through a plurality of jet channels and a flow disruptor assembly to receive the fluid from the jet nozzle assembly to generate a flow path of the fluid. The liquid flow device also includes a chamber assembly connected to the flow disruptor to receive the fluid from the flow disruptor assembly and an outlet assembly, open to an external environment to receive the fluid from the chamber assembly and output the fluid with a laminar flow pattern.

A nozzle is provided herein for ophthalmic dispensers which is configured to accommodate microdosing. The nozzle includes a converging pathway. Preferably, the pathway converges so as to impart momentum to liquid passing therethrough through an increase of velocity. A tapered portion may be provided flared openly from the inlet to best accept liquid flow thereinto and provide a funneling effect into the flowpath. Preferably, the flowpath terminates at an outlet which is internally un-radiused and circumscribed by a chamfered surface.

A concentrator nozzle attachment for a blower device is disclosed that increases the airflow velocity of the blower without sacrificing the field of the jetting air. The concentrator nozzle is formed of an outer ring with a centrally located guide surface and is placed at the exit of an air tube. As the air exits the air tube, it's forced to flow around the guide surface, thus increasing its velocity. The attachment is secured to the end of the air tube and so does not alter the outer diameter through which the air exits. In this way, air velocity is increased without reducing its effectiveness.

A spray head for a power sprayer configured to generate a continuous sheet-like water shield around a center stream of water. A water delivery device for use with a sink may produce a stream of water surrounded by a continuous shield of water.

An above-ground swimming pool is provided. The pool includes a bottom surface with side walls extending upwardly therefrom to define an inner volume for receiving water. The pool further includes top edge portions mounted on a top perimeter of the side walls and caps mounted between adjacent top edge portions. The pool also includes at least one water module adapted to connect to and operate with the above-ground swimming pool. The water module has a module base connectable to the top perimeter of the side wall of the swimming pool, a module casing extending upward from the module base and having a distal opening; and a supply system provided within the module casing and having a discharge opening for supplying water out of the supply system and through the distal opening of the module casing to enter an inner volume of the above-ground swimming pool.

The inventive concept relates to a liquid dispensing nozzle and an apparatus for treating a substrate. The liquid dispensing nozzle includes a first fluid channel that is formed in the nozzle and through which a processing liquid flows and a second fluid channel in communication with the first fluid channel, the second fluid channel being connected to a dispensing end of the nozzle. The second fluid channel has a larger width than the first fluid channel, and a central axis of the first fluid channel and a central axis of the second fluid channel are connected with each other in a straight line.
