The skirt (20) has a plurality of air ejection nozzles (40, 42, 44, 46) arranged in said skirt (20) to eject jets of air forming shaping air suitable for shaping the jets of coating product, said air ejection nozzles (40, 42, 44, 46) comprising at least three separate series of nozzles (41, 43, 45, 47) each made up of a plurality of air ejection nozzles (40, 42, 44, 46) fluidly connected to a shared supply chamber, specific to said series of nozzles (41, 43, 45, 47).

A process for making multiparticulates, comprising providing a molten feed comprising an active ingredient and an excipient, and providing a spinning disc sprayer comprising a rotating disc having a feed-receiving surface driven from above by a hollow drive shaft, wherein axes of rotation of the hollow drive shaft and rotatable disc are coaxial and a downward end of the hollow drive shaft is disposed with a distributor for regulating flow of the molten feed into the well, the distributor and the well together configured for providing a substantially radial, uniform outward flow of the molten feed across the feed-receiving surface.

The present application relates to a cartridge paint refilling device. More specifically the subject matter of the application relates to cleaning the paint adhered to the feed tube of the cartridge and prevent reduction of the painting quality and undesirable rotation caused by the paint residue. An annular flow path extending from a base end side towards a front end side in the insertion direction is disposed between the feed tube of the cartridge and the feed tube insertion hole of the cartridge supporting member. The cartridge supporting member is provided with a feed tube cleaning pipeline whose upstream side is connected with the circulation pipeline disposed at the cartridge supporting member and whose downstream side becomes a cleaning fluid discharge port and pens at the base end side of the annular flow path; and a pipeline witching valve which blocks communication between the circulation pipeline and the feed tube cleaning pipeline when the paint and the cleaning fluid are supplied to the paint chamber of the cartridge, and enables communication between the circulation pipeline and the feed tube cleaning pipeline when the cleaning fluid is supplied to the annular flow path.

An electrostatic atomizer can include a paint supply path configured to supply paint to a paint discharge section; and a high voltage supply path configured to supply a high voltage to a discharge electrode, wherein the discharge electrode comprises a semi-conductive material, and wherein the high voltage supply path includes a high resistance near the discharge electrode, and is electrically segregated from the paint supply path.

A bearing air passage through which bearing air is supplied toward an air bearing of an air motor and a turbine air passage through which driving air is supplied toward a turbine are provided in a housing. An annular space surrounding the air motor is provided between the housing and a cover. A bearing air branch passage connecting the annular space and the bearing air passage to each other and a turbine air branch passage for connecting the annular space and the turbine air passage to each other are provided. The air branch passages lead a part of the compressed air to the annular space and keep the cover in a heated state.

An in-situ applicator for applying a composition in a pipe comprises a flow diverter configured to receive a composition and eject the composition from at least one outlet. The applicator also comprises a hollow conical body having a narrow end, a broad end, and an interior surface configured to receive the composition ejected from the flow diverter. The conical body also has a plurality of holes forming a band that wraps circumferentially around the conical body which defines a flow region on the interior surface between the band and the narrow end. The band includes first holes adjacent to the flow region where each of the first holes has a first average diameter and second holes disposed between the first holes and the broad end, each of the second holes having an average diameter greater than the first diameter.

A spray nozzle includes a transmission component and a fan blade assembly. The fan blade assembly is connected to the transmission component, and can rotate with respect to the transmission component to create a vacuum inside the fan blade assembly, so that the liquid to be atomized under atmospheric pressure can enter the fan blade assembly through the transmission component. The fan blade assembly can also drive the liquid in the fan blade assembly to rotate so as to atomize the liquid and eject it from the fan blade assembly. The liquid in the fan blade assembly rotates with the fan blade assembly. A sprayer includes a body and the spray nozzle.

A sprayer includes a housing assembly, a spray nozzle assembly and a fan assembly. The housing assembly is connected to the spray nozzle assembly. The housing assembly is configured to hold liquid, and the fan assembly is configured to generate air flow. The spray nozzle assembly is configured to atomize and spray the liquid from the housing assembly, and blowout the air flow generated by the fan assembly. When the blowing is needed, the air flow generated by the fan assembly passes through the spray nozzle assembly and flows outward. When the spraying is needed, the spray nozzle assembly atomizes and sprays the liquid from the housing assembly. The sprayer is capable of blowing and spraying, which enables the spray to have an improved applicability.

A sprayer includes a spray nozzle, a blower and a sprayer housing. The sprayer housing is configured to contain a liquid. The spray nozzle and the sprayer housing are connected. The spray nozzle is configured to spray the liquid out from the sprayer housing. The blower is fixedly connected with the spray nozzle, and the spray nozzle is connected to the sprayer housing through the blower. The blower is rotatable with respect to the sprayer housing so as to adjust the angle of the blower with respect to the sprayer housing, thereby enabling the angle of the spray nozzle to be adjusted with respect to the sprayer housing. The angle of the spray nozzle with respect to the sprayer housing is adjustable, so the spray nozzle is capable of ejecting the liquid at different angles with respect to the sprayer housing without moving the sprayer.
