Embodiments for producing un-agglomerated, monodisperse droplets using a liquid sheet are provided. Nozzles with exit slit openings shape a spray liquid into a thin liquid sheet as the spray liquid exits from the slit opening. Stable multi-jet operation is achieved by including notches along the edge of the slit. The notches separate the liquid sheet into multiple jets to provide anchoring and stable multi-jet operation. In some embodiments, the liquid sheet electrospray techniques and nozzles described herein provide high mass throughput and versatile multiplexing spray systems while reducing the engineering effort and high manufacturing cost

The nozzle device comprises an opening configuration for emitting the emission medium and is distinguished particularly in that the opening configuration comprises at least two openings for emitting at least two jets of the emission medium and the at least two openings are oriented inwardly so that the at least two jets approach one another toward the emission side.

The disclosure relates to a nozzle device for dispensing a viscous application medium in the form of at least one jet (onto a component, preferably for the encircling application of the application medium onto a rabbet, edge or transition joint of the component (100), wherein the at least one jet defines a jet width. The nozzle device comprises an opening configuration for forming at least one slit opening to dispense the application medium and is in particular distinguished in that the opening configuration is concave to effect a narrowing of the jet width towards the dispensing side. The disclosure also relates to an associated method.

The disclosure relates to a nozzle device for emitting at least one emission medium onto a component, preferably onto a fold, an edge or a transition joint of the component. The nozzle device comprises at least two nozzle plates arranged adjoining one another, wherein a first nozzle plate comprises at least one opening for emitting at least one emission jet and a second nozzle plate comprises at least two openings for emitting at least two emission jets.

[Problem] To enable to stabilize the coating weight of the molten metal on the steel strip.

[Solution] There is provided a method for manufacturing a gas wiping nozzle provided with a pair of lip parts provided facing each other and a slit formed as a gas ejection port between the pair of lip parts and blowing a gas from the slit against a steel strip pulled up from a plating bath so as to adjust a thickness of a molten metal film deposited on a surface of the steel strip, which method for manufacturing a gas wiping nozzle comprising a fitting step of fitting fitting projections provided at one lip part with fitting holes provided at another slip part and a fastening step of fastening the pair of lip parts together in the fitted state where the fitting projections are fitted with the fitting holes, two pairs of the fitting projections and the fitting holes provided separated by a distance in a width direction of the steel strip, relative movement between the pair of lip parts in a thickness direction of the steel strip restricted in the fitted state, the distance between the fitting projections and the fitting holes in the thickness direction of the steel strip satisfying the predetermined condition.

According to an embodiment of the invention, a coating head of a mist coating film formation apparatus including a main body is provided. The main body includes a top plate in which a supply port capable of supplying one of a cleaning liquid or a mist of a source material solution is provided, a bottom plate provided below the top plate in a vertical direction, and a sidewall provided between the top plate and the bottom plate; and the sidewall includes an upper end and a lower end connected respectively to the top plate and the bottom plate and forms an interior space with the top plate and the bottom plate. The sidewall includes a slit spraying the mist externally from the interior space, and a recovery port capable of recovering the supplied cleaning liquid or a mist coalescing in the interior space. The bottom plate includes a slope having a height becoming lower from an inner perimeter of the sidewall toward the recovery port.

A nozzle for atomizing coating materials, in particular coating powder, includes a housing, which has an inlet-side opening and an outlet-side opening, and the openings are connected to each other by a passage channel. The housing has an inner housing part, which defines the passage channel, and an outer housing part, which is designed to detachably connect the nozzle to a coating device. In order to optimize the production process for the nozzle and to reduce costs, the inner housing part and the outer housing part are designed as separate individual pieces.

The invention relates to a nozzle arrangement (1) for applying fluids (20), in particular thermoplastic materials, to a substrate (21), wherein the nozzle arrangement (1) comprises a base body (14), which can be connected, preferably exchangeably, to a mounting region of a distributor (30), and a front lateral surface. According to the invention, it is provided in particular that a recessing region (3) is configured in the front lateral surface of the base body (14), wherein at least one first outlet opening (4) and preferably a plurality of adjacently arranged first outlet openings (4) for the fluid (20) to be applied to the substrate (21) is configured in the recessing region (3) of the front lateral surface of the base body (14)

A sealing agent (25) sent from a nozzle tube (36) to a nozzle main body (37) is passed through a main body flow channel portion (37a), a connecting portion (37c), a first flow channel portion (37b), and plural second flow channel portions (37d), sent to a chamber (37e), and discharged from a nozzle port (37f) to the outside. Since the second flow channel portions (37d) are smaller than a downstream end of the first flow channel portion (37b), the sealing agent (25) in the first flow channel portion (37b) is vigorously sent to the chamber (37e), and discharged from the nozzle port (37f) to the outside. As a result, substantially the same quantity of the sealing agent (25) is discharged in the entire range of the chamber (37e).

An air outlet device is disclosed herein. The air outlet device includes a plenum body portion, the plenum body portion defining an air chamber therein, the plenum body portion including an air inlet configured to be coupled to a supply air source for supplying air to the air chamber; an air nozzle portion fluidly coupled to the plenum body portion and including a nozzle inlet and an exit orifice, the air nozzle portion configured to discharge the air from the air chamber at a substantially uniform velocity through the exit orifice; and an air nozzle extension fluidly coupling the air chamber of the plenum body portion to the nozzle inlet of the air nozzle portion, the air nozzle extension being configured to increase an efficiency of the air outlet device by decreasing the pressure drop that occurs when the pressure energy of the air is converted to kinetic energy.
