A spray nozzle assembly having a nozzle body and a downstream air cap. The air cap has a central opening through which liquid is directed and a plurality of circumferentially spaced air passages oriented at a compound angle to the central flow axis of the air cap opening for directing pressurized air flow streams that interact with discharging liquid for atomizing the liquid while imparting a tangential direction to the atomized liquid for enhanced atomization and a swirling movement into a full cone spray pattern. The air cap may have an integrally formed spray tip or a separate spray tip may be associated with the nozzle body. The air cap may be formed with a downstream conical recess into which liquid and air streams are directed, or alternatively, be designed for atomizing liquid internally within the air cap.

A device for spraying adhesive onto a substrate or workpiece, for example, an automotive workpiece, includes at least one spray nozzle for discharging the adhesive having at least two adhesive inlets and at least two regions of adhesive outlets. One of the regions of adhesive outlets which can be supplied separately with a width of less than 25 mm is connected to precisely one of the adhesive inlets.

A nozzle arrangement applies fluids, in particular thermoplastic adhesives, to a substrate. The nozzle arrangement and the substrate move relative to one another in a first direction. The nozzle arrangement has a main body which is exchangeably connected to a mounting region of a distributor and which has an end-side side surface extending in a second direction running at least substantially perpendicular to the first direction. The end-side side surface of the main body can have mutually adjacently arranged first outlet nozzles for the fluid to be applied formed in a first row extending along the second direction and mutually adjacently arranged second outlet nozzles for a second fluid formed in a second row extending along the second direction and that is parallel to the first row.

The present invention relates to a spray head for a paint sprayer, in particular a paint spray gun or a paint spray lance, for generating a paint jet. Here, an air cap comprises two curtain air channels whose outlets are arranged between air horns, and whose outlets lie opposite each other in relation to a longitudinal axis of a through-opening of the air cap.

An object of the present invention is to provide an apparatus for producing nanofibers and a nozzle head use for the same which can be manufactured by drilling and is capable of efficiently carrying molten resin on a gas flow.

A nozzle head 20 of an apparatus for producing nanofibers 1 comprises a raw material discharge surface 22 on which a raw material flow passage 25 for discharging a liquid raw material is arranged, and a gas discharge surface 23 which is arranged with an angle (0<90) toward the raw material discharge surface 22 and on which a gas flow passage 26 for ejecting gas is arranged. The raw material flow passage 25 is orthogonal to the raw material discharge surface 22, the gas flow passage 26 is orthogonal to the gas discharge surface 23, and the raw material flow passage 25 and the gas flow passage 26 are arranged so that the liquid raw material discharged from the raw material flow passage 25 meets gas ejected from the gas flow passage 26.

A static spray mixer for the mixing and spraying of at least two flowable components is proposed having a tubular mixer housing (2) which extends in the direction of a longitudinal axis (A) up to a distal end (21) which has an outlet opening (22) for the components, having at least one mixing element (3) arranged in the mixer housing (2) for the mixing of the components as well as having an atomization sleeve (4) which has an inner surface which surrounds the mixer housing (2) in its end region, wherein the atomization sleeve (4) has an inlet channel (41) for a pressurized atomization medium, wherein a plurality of grooves (5) are provided in the outer surface of the mixer housing (2) or in the inner surface of the atomization sleeve (4) which respectively extend toward the distal end and which form separate flow channels (51) between the atomization sleeve (4) and the mixer housing (2) through which the atomization medium can flow from the inlet channel (41) of the atomization sleeve (4) to the distal end (21) of the mixer housing (2). Each flow channel has a respective changing inclination toward the longitudinal axis (A) in the direction of flow.

The liquid ejecting device uses pressurized gas to eject liquid as a spray of fine particles and is provided with internal gas-flow passageway to supply pressurized gas, and a nozzle section with a slit-shaped liquid ejecting opening to discharge liquid. The nozzle section is near the end of the an elongated main unit of the liquid ejecting device, and gas jet openings to discharge pressurized gas are established between inclined nozzle surfaces and sidewalls of the main unit. The liquid ejecting opening is connected with liquid-flow passageway and the gas jet openings are connected with the gas-flow passageway. Viewed in cross-section, the inclined nozzle surfaces are formed such that their extensions intersect above the liquid ejecting opening on a line extending from the liquid ejecting opening, and pressurized gas is discharged as jets along the inclined nozzle surfaces to intersect in a manner that sandwiches the liquid in between and breaks-up the liquid-flow to produce a spray of fine particles.

A semi concentric enhanced parallel path pneumatic nebulizer is described which has a nebulizer body with an inner capillary and outer passage, with liquid flow in one and gas flow in the other. The passage extends around the inner capillary and contacts the inner capillary's outer walls at the tip of the nebulizer body in a nozzle end. The inner capillary has a single lumen which conveys a fluid from an inlet on one end of the nebulizer to an exit port in the nozzle end. The inner capillary seals the passage within the nozzle end and has an opening in the capillary wall extending from the outermost edge of the capillary to the passage in the nebulizer body, allowing the fluid in the passage to exit the nebulizer through an exit port in the capillary wall. The fluids, being a gas and a liquid, interact to form an aerosol.

Provided are air caps for liquid spray head assemblies and/or for liquid spray guns. Specifically provided are molded air caps with face geometry inserts. Face geometry inserts provided herein may be effective to provide refined spray patterns. The face geometry inserts are components that are self-aligning in that location, size, and spacing of air and/or liquid openings are designed into in a single piece. The air caps comprise a base member comprising: a base member body, at least one pair of exit air openings, a nozzle tip opening; and a face geometry insert comprising a pair of shaping air apertures and being retained to the base member body.

A film forming apparatus includes a spray nozzle, a first chamber, a first gas supply port, a second chamber, a through hole, and a mist outlet. A solution transformed into droplets that is to be sprayed from the spray nozzle is housed in the first chamber and transformed into a mist in the first chamber by gas injected from the first gas supply port. The solution in mist form moves from the first chamber through the through hole to the second chamber and is misted onto a substrate from the mist outlet of the second chamber.
