A spray tip for a fluid applicator includes a stem configured to be inserted into the fluid applicator. The stem includes a stem pre-orifice portion and an insert receiving portion. The spray tip includes a pre-orifice insert having an inlet and an outlet. The pre-orifice insert is disposed within the insert receiving portion and disposed against a rearward shoulder of the stem.

Provided are a method of manufacturing an orifice and an orifice manufactured by the same. An object of the present invention is to provide a method of manufacturing an orifice spraying a very small amount of fluid in ultra-high pressure and very low temperature environments and reducing a volume and a mass, and an orifice manufactured by the same. More specifically, an object of the present invention is directed to providing a method of manufacturing an orifice capable of manufacturing an orifice effectively realizing a desired hydraulic performance by a simple manufacturing method of allowing a channel region having a cross section close to a rectangular shape to be formed by pressing a part of a capillary pipe, and an orifice manufactured by the same.

A nozzle system comprising a nozzle apparatus (610) and a pipeline (614), the nozzle apparatus attached to the pipeline such that there is fluid communication therebetween, the nozzle apparatus having a first inlet (631), a second inlet (622) and an outlet, wherein the nozzle apparatus extends into the pipeline such that at least a portion of the first inlet (631) is in the centre of the pipeline, that is within 15% of the central axis of the pipeline; and the second inlet (622) is within the pipeline but outwith the centre of the pipeline, the second inlet comprising a filter with at least one, normally at least four, linear apertures (625) therein, often parallel to a main axis of the nozzle apparatus (610). Preferably the first inlet is a larger aperture than the second inlet, and is provided on an end of the nozzle apparatus and the second inlet is provided on a side of the nozzle apparatus. An advantage of certain embodiments of the invention is that where debris builds upon an inside face of the pipeline (concentric corrosion), fluid can still flow through the inlet provided in the centre of the pipeline, and so nozzle apparatus as described herein are less liable to blockages.

[Problem] To enable to stabilize the coating weight of the molten metal on the steel strip.

[Solution] There is provided a method for manufacturing a gas wiping nozzle provided with a pair of lip parts provided facing each other and a slit formed as a gas ejection port between the pair of lip parts and blowing a gas from the slit against a steel strip pulled up from a plating bath so as to adjust a thickness of a molten metal film deposited on a surface of the steel strip, which method for manufacturing a gas wiping nozzle comprising a fitting step of fitting fitting projections provided at one lip part with fitting holes provided at another slip part and a fastening step of fastening the pair of lip parts together in the fitted state where the fitting projections are fitted with the fitting holes, two pairs of the fitting projections and the fitting holes provided separated by a distance in a width direction of the steel strip, relative movement between the pair of lip parts in a thickness direction of the steel strip restricted in the fitted state, the distance between the fitting projections and the fitting holes in the thickness direction of the steel strip satisfying the predetermined condition.

A steam dispersion system including insulation is disclosed. The steam dispersion system may include a steam dispersion tube with at least one opening defined on an outer surface of the steam dispersion tube and a hollow interior. The insulation covers at least a portion of the steam dispersion tube, the insulation defining an opening aligned with the opening of the steam dispersion tube, wherein the insulation meets 25/50 flame/smoke indexes for UL723/ASTM E-84 and has a thermal conductivity less than about 0.35 Watts/m-K (2.4 in-hr/ft{circumflex over ()}2 deg F.). A nozzle defining a throughhole may be placed within the opening of the steam dispersion tube, the throughhole being in fluid communication with the hollow interior of the steam dispersion tube to provide a steam exit.

A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

A method of fabricating a fuel injector nozzle comprising the steps of: (a) forming a first microstructured pattern in a first material; (b) replicating the first microstructured pattern in a second material to make a first mold comprising a second microstructured pattern in the second material; (c) replicating the second microstructured pattern in a third material to make a second mold comprising a third microstructured pattern comprising a plurality of microstructures in the third material; (d) replicating the third microstructured pattern in a metal material to make a replicated structure; and (e) removing the third material resulting in a nozzle having a plurality of through-holes through the metal material and corresponding to the plurality of microstructures in the third microstructured pattern. Each of the plurality of through-holes has a hole wall connecting a hole entry to a hole exit, and the hole wall of at least one through-hole has a side that curves from its hole entry to its hole exit.

Methods of making nozzles are disclosed. More specifically, methods of making nozzles that may be used as components of a fuel injection system are disclosed.
