Thus, it is possible to prevent external air from entering the nozzle head, and the coating material from leaking to the outside of the nozzle head.

An electrostatic sprayer operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer includes an elongated body having a downstream spray nozzle assembly through which electrically charged liquid is directed via a central feed tube within the nozzle body and atomizing air is supplied via an annular passage about the liquid feed tube. In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly having a plurality of circumferentially spaced metallic spray tips. In another embodiment, the spray nozzle is an internal mix nozzle assembly having a spray tip with an internal mixing chamber for atomizing liquid prior to discharge.

An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

An annular discharge device for discharging a gluing composition onto glass fibres includes at least one distribution circuit for the gluing composition and a plurality of spray nozzles fluidically connected with the distribution circuit and distributed over the perimeter of the annular discharge device for discharging the gluing composition onto the glass fibres intended to pass into the annular discharge device defined by an axis of revolution, each spray nozzle being oriented towards the interior of the annular discharge device with an angle of inclination determined in relation to the plane of revolution of the annular discharge device. At least two spray nozzles arranged consecutively on the perimeter of the annular discharge device are disposed so as to have an orientation with respect to the plane of revolution of the annular discharge device each with a different angle of inclination with respect to one another.

An electrostatic sprayer device includes a housing, an electrostatic module inside the housing, and a reservoir having a cavity adapted to contain a fluid. A nozzle fluidly connected to the reservoir emits electro-statically charged fluid. A syringe assembly communicates with a fluid pathway that leads to the nozzle such that the nozzle can expel fluid from the syringe assembly in combination with the fluid from the reservoir.

A delivery device for an automobile trauma-reducing safety system includes a base component on which a membrane is supported deflated in an initial state prior to an automobile collision and is inflated in an activated state in response to a triggering event. A spray valve is movably coupled to the base component and is concentrically-aligned with the membrane. The spray valve includes exhaust nozzles, is in a retracted position in the initial state, and is movable towards an extended position in the activated state. A containing area stores a chemical liquid in the initial state and is formed between the spray valve and the deflated membrane. The chemical liquid is forced by the inflated membrane in the activated state to move the spray valve from the retracted position towards the extended position, the chemical liquid being expelled through the exhaust nozzles for reducing trauma to an automobile occupant.

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.
