A liquid ejecting head includes a nozzle. A sectional shape at a first-position in the nozzle in an ejection-direction is a first-external-shape, and a straight line extending in a second-direction orthogonal to both the ejection-direction and a first-direction being a longitudinal-direction of the first-external-shape and passing through a center of the first-external-shape in the first-direction is a first-center-line. A first-width corresponding to a maximum width in the second-direction in a portion of the first-external-shape on one side in the first-direction with respect to the first-center-line is at a third-position in the first-direction. A second-width corresponding to a maximum width in the second-direction in a portion of the first-external-shape on the other side in the first-direction with respect to the first-center-line is at a fourth-position in the first-direction. A distance between the third-position and the fourth-position is greater than the first-width and the second-width.

A spray tip is configured to atomize thick, viscous fluids. The spray tip includes a pre-orifice piece having an inlet orifice that defines a first restriction in a fluid path through the spray tip. The spray tip also includes a tip piece having an outlet orifice that defines a second restriction in the fluid path. The first and second restrictions are the portions of the fluid path having the smallest flow areas. A cross-sectional area of the outlet orifice is greater than a cross-sectional area of the inlet orifice.

A kitchen shower includes a water outlet mechanism, a switching mechanism and a brush mechanism. The water outlet mechanism is provided with a shower water outlet, a sheet water outlet and a bubble water outlet. The switching mechanism includes a main body, a first switching assembly, a second switching assembly and a third switching component. The first switching assembly is used to switch whether the kitchen shower is out of water, the second switching assembly is used to switch the kitchen shower out of sheet water, and the second switching assembly is used to switch the kitchen shower out of shower water or bubble water. The brush mechanism is detachable and installed on the water outlet mechanism. The brush mechanism can make the kitchen shower clean at the same time of water outlet, so that the cleaning effect is higher.

A rectifying member capable of improving a collision force of a jet fluid, and a nozzle. A rectifying member includes rectifying elements each having a tubular casing and a division wall structure formed in the casing; the division wall structure includes partition walls, and has a circumferential division wall group being adjacent in a circumferential direction of an inner wall of the casing and having an extending partition wall, and an inside division wall group in an inside region of the fluid flow path.

Various embodiments for an adjustable flow nozzle system having a manifold with a plurality of adjustable flow nozzles in which the flow rate of each adjustable flow nozzle may be individually adjusted are described herein.

A system for the application of foamable chemical compositions is presented. The application system comprises an ergonomic handle/adapter removably attachable to a pressurized source of a foam product, the handle having inlet and outlet orifices or openings for flow of the foam product from the pressurized source to a nozzle, the nozzle having an outlet orifice for dispensing the foam product and an inlet orifice for connecting to a flexible tubular connecting member which interconnects the outlet orifice of the handle/adapter with the inlet orifice of the nozzle. The nozzle of the present invention includes design features to produce a fan shaped spray pattern of the foam product and to reduce the incidence of leakage or dripping of either moisture or the foam product at the nozzle's outlet. The tubular connecting member is flexible and therefore allows a user to spray foam into hard to reach places.

Various embodiments of modular dual vector fluid spray nozzles are disclosed. Embodiments of the nozzles are characterized by specially shaped fluid channels, impingement surfaces and exit orifices used to generate atomized mists of fluid under pressure. Embodiments of the nozzles are generally characterized by composite fluid spray density patterns having horizontal and vertical components, i.e., dual vector in nature. The nozzles disclosed are modular and may be easily installed or removed from a given fluid spray system, nozzle head, or fixture as dictated by any given application.

A medical device is provided for irrigation of a patient wound site. The device contains a tube having a proximal portion adapted to receive an irrigation solution, a distal portion having a nozzle and an intermediate portion for transporting the solution. The tube has a barrel portion that may be manipulated by a user to position the device relative to the wound site. A distinctive nozzle has a body formed with a distally leading channel presenting a semispherical first spatial conformation and a proximally leading opening formed in the body presenting a second spatial conformation intersecting the semispherical terminus. This geometry, derived from principles of flow mechanics discussed herein, defines what will be described as an “effective diameter” of the nozzle. An assembly and system utilizing the device am also disclosed. The invention utilizes a fluid-isolating durable peristaltic pump for a continuous flow of irrigation solution, along with a single use tube set that embodies the device.

A spray nozzle assembly for directing thin, straight line, high pressure liquid spray onto moving steel slabs for penetrating and removing scale buildup in steel processing operations. The spray nozzle assembly includes a liquid inlet defined by an upstream strainer and a downstream high impact attachment tube for accelerating liquid flow. A one-piece multi-stage liquid straightening vane segment is disposed within a central liquid flow passage of the nozzle assembly for more effectively reducing liquid turbulence of the high pressure liquid flow with resultant improved control in the tightness of the thin, flat spray panner. The one-piece vane segment further is adapted for efficient assembly and replacement in the spray nozzle assembly without the need for handling and precise alignment of a plurality of individual vane elements.
