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 nozzle apparatus comprising: an inlet, an outlet, a filter disposed between the inlet and the outlet, and, a container; wherein the nozzle apparatus defines a first flow path for particles too large for said filter and a second flow path towards the outlet for particles small enough for said filter; and wherein the container is provided downstream of the first flow path. In this way the pressure on the container downstream of the first fluid path causes the debris to accumulate therein and the nozzle is less liable to blockages. The apparatus is of particular use as a sprinkler system.

A nozzle needle for an injector for injecting fuel includes at least one guiding section with a recess and a guiding surface configured to rest against an inner surface of a nozzle body of the injector, the recess at least partially delimiting the guiding surface and being configured to allow a flow of fuel along the guiding section, and the guiding surface being guided about the longitudinal axis of the nozzle needle in a helical manner.

In a method for influencing the thread geometry of an internal thread of a first component of an injection device for internal combustion engines, which is provided for carrying high-pressure fluid, wherein the first component has a tubular end portion and an internal thread is formed on the interior surface of the tubular end portion, and a second component having an exterior surface on at least a portion thereof so as to be received in the tubular end portion of the first component wherein the exterior surface is threaded so said second component can be screwed and clamped against a support surface of the first component, and wherein the tubular end portion on the external side is acted upon by a radial compression force allowing a plastic deformation. The tubular end portion is transformed thereby in such a manner that the internal thread obtains an inner diameter (D) continuously decreasing towards the free end.

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 method for manufacturing a gas wiping nozzle provided with a pair of lip parts facing each other and a slit formed as a gas ejection port between the pair of lip parts and blowing gas from the slit against a steel strip pulled up from a plating bath to adjust a thickness of a molten metal film deposited on a surface of the steel strip, which method includes fitting fitting projections provided at one lip part with fitting holes provided at another slip part and fastening the pair of lip parts together in the fitted state, the fitting projections 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.

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^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 method of manufacturing an orifice is provided to make the orifice capable of spraying a very small amount of fluid in an ultra-high pressure and very low temperature environments. The method also makes it possible to provide the orifice with reduced volume and mass. More specifically, the method effectively realizes a desired hydraulic performance through a simple manufacturing method in which a part of a capillary pipe is pressed to form a channel region having a cross section close to a rectangular shape.

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.

The invention relates to a method for producing a nozzle, in which an injection orifice of the nozzle for dispensing fuel is produced by means of laser drilling, and a cavity is formed in the nozzle along the longitudinal expansion thereof. The method is characterised in that the cavity formed in the injector is produced after the injection orifice has been produced.
