The atomizing portion includes multiple miniature fluid control valves and an air assisted atomizing outlet. The PNVA assembly also includes a PNVA electronic module. The PNVA electronic module includes a microcontroller, at least one pulse width modulation driver, a wireless radio, a differential pressure sensor, and a laser targeting LED.

A massage nozzle includes a nozzle housing and a nozzle core detachably attached in the nozzle housing. The nozzle housing is split-type and includes a cover mounted in a hole of a wall of a hot tub, a nozzle seat and a fastener. The cover includes an end ring and a side wall extending from the end ring. The side wall is conformed with the hole. The nozzle seat includes an inlet and a spray end which has a surface conformed with the side wall. The nozzle seat passes through and detachably connects with the cover. The outer circumferential surface of the spray end contacts with an inner surface of the side wall. The fastener is detachably sleeved on the outer circumferential surface of the nozzle seat and cooperates with the cover to fix the nozzle seat to the hot tub. The installation is convenient and the cost is reduced.

The present invention provides unique pressure actuated valves and related methods that may be used in applications where a plurality of fluid emission devices are provided on a plurality of lines containing fluid under pressure, in order to prevent fluid from escaping from the fluid emission devices until a consistent threshold or predetermined level of fluid pressure is obtained in the lines, without causing significant water pressure and/or flow loss through the valves. Valves of the present invention include a housing having an upper body and a lower body that may be coupled together to form an inner chamber, the lower body having an inlet in communication with a source of fluid under pressure, the upper body having an outlet in communication with a fluid emission device. A hollow movable fluid transmission piston is provided in the chamber for communicating between the inlet and outlet. The chamber formed between the upper and lower bodies may be provided with cup seals at opposite ends of the chamber to reduce friction and prevent fluid from entering therein, and a side air vent. A wider lower end of the piston is urged toward the lower housing body using a biasing mechanism, which pushes an O-ring at the lower end against a stop to prevent fluid from entering into the hollow center of the piston. When fluid with a sufficient pressure is provided from the source, it pushes the O-ring away from the stop and against the urging of the biasing member, allowing fluid to flow around the stop, through the center of the piston, and out through the upper body into the fluid emission device. The vent in the chamber allows air inside the chamber (surrounding the biasing mechanism) to escape so that there is no added air pressure within the chamber to be overcome by the fluid pressure.

Constructive arrangement applied in an electrostatic spray nozzle for aircraft and helicopters, equipped with electrode insulation fins, a diffuser core with a dosing disc and a fan dosing tip with regulation for a conical jet and flat jet.

An electric-powered bulk material dispersing system and method of use. The electric power is provided by a battery system with one or more electric motors to replace traditional internal combustion engines. The electric motor or motors are used to provide pressure to one or more pumps that may be used in conjunction with various tubes, hoses or related conduit and spray nozzles in order to disperse a bulk material such as seed, mulch, compost, chipped wood, grain, hay, fertilizer, herbicide, pesticide, plastic pellets, salt, sand or the like that has been combined or suspended within a fluent material. In one form, the bulk material dispersing system may be used as a bulk hydroseeder.

A nozzle device for sorting objects by ejecting a gaseous media towards said object. The nozzle device nozzle device including: a nozzle unit including at least one nozzle; a nozzle bar including gas supply means for providing a gaseous media to said nozzle unit; and a nozzle fixation bracket adapted for holding said nozzle unit in place; said at least one nozzle including: an inlet for receiving the gaseous media; and having one outlet, having an outlet area, for ejecting the gaseous media towards an object to be sorted; a channel extending between said inlet and said outlet; an outlet portion surrounding at least said outlet, wherein said outlet portion includes a flexible material, which deflects upon ejection of the gaseous media, received from said nozzle bar, through said outlet whereby said outlet area increases. Also, a system for sorting objects.
