An Actuator that facilitates a Hydra Pneumatic Valve while insuring complete evacuation of product by use of a dual MBU (Mechanical Breakup) nozzle area that can be fixed at a preset or variable dispensing mode for application of a half and half mix or a ratio mix of product to air, atomized output. Aside from utilizing 95% of the Preload pressure as part of the effective spray output, the Actuator Outer Body may be ergonomically or aesthetically designed. The present invention will have variations of customization to suit a variety of products that require higher pressures, not being capably achieved with present standard Bag-ON-Valve Systems without having heavier wall containers which adds expense and hazards accordingly.

A particle diameter is decreased and a surface area per unit flow amount is increased by spraying a VOC-containing liquid from a spraying device spraying that is a two-fluid nozzle in a vacuum container, so that only water in the VOC-containing liquid can be greatly evaporated and exhausted, and a concentrated VOC-containing liquid having high concentration can be refined and processed.

A mist pump of a cosmetic container according to the present invention includes: a cap housing configured to be able to atomize contents by compressing external air introduced together with the contents in a cosmetic container and then discharging the contents in a whirlwind form by means of the compressed air; a piston housing; a compressing chamber formed between the cap housing and the piston housing; a piston formed to eject the compressed air and the contents while ascending; an opening and closing part that is formed between an inner surface of the piston housing and an outer surface of the piston, and through which the contents and the compressed air are ejected when the piston descends, and the external air is introduced into the compressing chamber when the piston ascends; and a pressurizing cap coupled to include an atomizing part that atomizes the contents by discharging the contents together with the compressed air in the whirlwind form through a nozzle passage formed in an upper end of the piston. Accordingly, the mist pump of the cosmetic container has the effects in that the mist pump may be used without being limited by the size of the cosmetic container, by virtue of external air compression, and a high level of stability can be achieved.

The present invention includes a mist generator that generates a mist of a raw material of a film to be formed, and a mist jet nozzle that jets the mist generated by the mist generator to a substrate on which a film is to be formed. The mist jet nozzle includes: a main body having a hollow portion; a mist supply port that supplies the mist; a spout that jets the mist to the outside; a carrier gas supply port that supplies a carrier gas; and a shower plate having a plurality of holes formed therein. By the arrangement of the shower plate, the hollow portion is divided into a first space connected to the carrier gas supply port and a second space connected to the spout. The mist supply port is connected to the second space.

A method for producing a spray jet from a liquid/gas mixture with a two-component nozzle having a nozzle housing, including the steps of blending a supplied liquid and a supplied gas and producing a spray jet consisting of gas and liquid drops, producing a gas jet and mixing of gas jet with the spray jet.

An acoustic force assisted painting system has a housing, at least one nozzle and at least one acoustic emitter. The housing has a conduit for receiving paint from an external source into the housing. The at least one nozzle is disposed in the housing. The at least one nozzle has an inlet that is fluidly connected to the conduit to receive paint from the conduit. The at least one nozzle has an outlet that dispenses paint. The least one acoustic emitter is disposed in the housing at a location downstream of the inlet with respect to the conduit.

A nozzle includes a nozzle housing defining a first flow path having a first inlet at a first end of the nozzle housing and a first outlet at a second end of the nozzle housing. The nozzle housing also defines a second flow path having a second inlet at an outer surface of the nozzle housing and a second outlet in a side wall of the nozzle housing defining the first flow path, the second outlet defining a Coanda profile and having an annular shape around the first flow path. The nozzle housing defines a third flow path having a third inlet at the outer side surface of the nozzle housing and a third outlet in the side wall defining the first flow path, the third outlet comprising a plurality of holes arranged in an annular pattern around the first flow path.

Disclosed is a compact spraying module for spraying a liquid in the form of droplets for treating a target. The module includes a spraying unit including a nozzle containing at least one spraying member and a fan that is capable of generating a carrying air flow in the nozzle and of carrying the droplets originating from the member to the target. The module includes its own liquid supply system that and includes an electric pump, an electronic control and monitoring unit, a holder that keeps the pump near the spraying unit, an individual communication interface, and a power supply interface. Also disclosed is a system for spraying and controlling a plurality of such modules and to a method for controlling modules of such a system.

Disclosed is a spraying unit intended for spraying a liquid onto vegetation and including: a nozzle formed by a tube, a rotatable atomizer, and a fan generating a carrying air flow around the atomizer, a drive system, and a transport unit for transporting the liquid to the atomizer, which is capable of breaking the liquid up into droplets. The nozzle encloses a body surrounded by the carrying air flow and including a rotatable portion formed by the rotatable atomizer, the rotation of which causes droplets in the carrying air flow to be propelled, preferably in a direction substantially perpendicular to the longitudinal axis. Also disclosed is a compact spraying module including such a unit and to a spraying and control system including a plurality of such modules.

There is provided a loop flow type bubble generation nozzle capable of improving the bubble generation efficiency compared to conventional nozzles without reducing the bubble generation efficiency even when liquid containing impurities is used. A loop flow type bubble generation nozzle 10 includes a tubular bottomed member 1 having a circular cross section and a tubular member 2 which is fitted into the other end side of the bottomed member 1. A substantially cylindrical space surrounded by the bottomed member 1 and the tubular member 2 serves as a loop flow type gas-liquid stirring and mixing chamber 6. The tubular member 2 has, on the center thereof, an inflow hole 7 which is capable of allowing liquid and gas to flow therein, and a first jet hole 8a and a second jet hole 8b which are capable of jetting liquid and gas. The inflow hole 7 is formed in a tapered shape whose diameter continuously expands from the first jet hole 8a toward the loop flow type gas-liquid stirring and mixing chamber 6. A plurality of cut-away parts 7a are formed on an end face of the inflow hole 7, the end face facing the loop flow type gas-liquid stirring and mixing chamber 6.
