An aerosol actuator has a main body member, a nozzle member defining an outlet opening, and a selector member. The outlet opening defines a fluid flow direction. The selector member is moved to obtain different fluid spray patterns. The selector member is distal to the nozzle member and the fluid flow direction.

A viscous liquid feed nozzle has a nozzle body having a thin and long hole with a front end serving as a feed port. The nozzle is used with a viscous liquid feed unit to feed a viscous liquid such as a viscous adhesive from the feed port. The nozzle has a lubricative plated layer at least on the inside and outside of the feed port. The lubricative plated layer is formed by electroless plating by immersing the nozzle in a plating tank containing a lubricative plating solution. A base end of the nozzle body may have a wide port. In this case, the lubricative plated layer is formed by immersing the nozzle body in the plating tank containing the lubricative plating solution so that the lubricative plating solution enters the wide port and by applying pressure or gravity to the lubricative plating solution in the wide port to pass the lubricative plating solution through the thin and long hole of the nozzle body and discharge the same from the feed port. The viscous liquid feed nozzle with the lubricative plated layer is capable of stably feeding a very small quantity of a viscous liquid.

A spray gun, which contains: a coating liquid nozzle configured to discharge a coating liquid from an outlet; and a flow channel forming member configured to surround an outer perimeter surface of the coating liquid nozzle to form an air flow channel, through which atomizing air passes, between the outer perimeter surface of the coating liquid nozzle and the flow channel forming member, wherein the spray gun is configured to atomize the coating liquid with the atomizing air to spray the atomized coating liquid to a coating target, wherein a gap T of the narrowest part of the air flow channel is 0.48 mm or smaller, and wherein a ratio T/L of the gap T to a distance L from the narrowest part to an apical surface at which the outlet of the coating liquid nozzle is open is 0.60 or greater.

A modular liquid distribution system in which each module has a module body, a spray nozzle, and a cyclically operable piston for controlling the dispensing of high viscous liquids from the spray nozzle. Each spray nozzle has a nozzle body with a liquid inlet and a tear dropped shaped pintle which together with the nozzle body defines an expansion chamber that reduces velocity of the liquid sufficient to be dispensed in small droplet form without splattering. In one embodiment, the nozzle body has a discharge orifice sized smaller than the outer diameter of the expansion chamber for accelerating liquid flow upon discharge sufficient to enhance consistent and repeatable breaks in the cyclically controlled fluid flow stream for enabling the discharge of smaller and more consistent volumes.

A sprayer system including a wand, a rotary arm, a motor, a housing, a support, and a controller or control panel. The wand has a nozzle at one end. The rotary arm rotates around a first axle, and is connected at a distal end through a bearing to an opposite end of the wand. The housing covers or encloses a part of the wand, the rotary arm, and a rotatable ring through which the wand passes. The motor drives rotation of the rotary arm. The support mechanically supports the housing. The controller/control panel controls rotation of the rotary arm. The wand, the rotary arm and the ring are configured so that rotation of the rotary arm causes the nozzle to move in a circular, elliptical and/or oval pattern. Methods of making and using the sprayer system and software for controlling the system are also disclosed.

The showerhead has a hollow body (10) provided with an inlet nozzle (11) and with a sieve (C) perforated by holes (13) and a cleaning device (40) carrying a plurality of lower pins (41) and displaceable, in the interior of the hollow body (10), between an inoperative position, with the pins (41) spaced from the sieve (C), and an operative position, with each pin (41) introduced into one hole (13) of the sieve (C) and defining at least one water outlet with the hole (13). A driving element (50) is associated with the inlet nozzle (11) and is affixed to the cleaning device (40), in order to maintain it in the inoperative position, while the hydraulic pressure in the inlet nozzle (11) is less than a reference value and displacing the cleaning device (40) to the operative position, when the hydraulic pressure reaches the reference value. A biasing element (60) displaces the driving element (50) and the cleaning means (40) to the inoperative position, when the hydraulic pressure is lower than the reference value.

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser (100), configured to draw fluid up from a container. A nozzle assembly can include a nozzle (160), and a nozzle slide (112). The nozzle slide can be configured to slide and/or rotate relative to the shroud (102) to provide different dispensing modes. In alternative examples, the nozzle (160) can be configured to rotate in 30 degree increments relative to the shroud (102) to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

A firefighting nozzle comprises an elongated barrel having a inlet opening at one end for engaging a source of fluid under pressure and a discharge opening at an opposite end for engaging a discharge element for dispensing the fluid under pressure. A valve arrangement includes a slide valve element slidably mounted within the barrel for reciprocating movement along the length of the barrel to adjust the flow of fluid through the barrel. The nozzle includes a pistol grip trigger assembly mounted on the barrel that includes a segment gear pivotably for engaging a toothed surface of the slide valve element so that rotation of the segment gear causes reciprocation of the slide valve element. A four-bar linkage arrangement is incorporated between a manually actuated trigger to translate depressing the trigger to controllable reciprocation of the slide valve element. The four-bar linkage provides a mechanical advantage that allows the firefighter to easily control the trigger and thus the fluid discharge from the nozzle.
