The inventive concept relates to a swirler. According to an aspect of the inventive concept, there is provided a swirler including a casing, a pilot body disposed in the casing, and a plurality of vanes arranged along a circumference of the pilot body, wherein at least a part of the vane protrudes further to a downstream than an end portion of the pilot body.

A nozzle includes a nozzle body defining a liquid circuit extending from a liquid inlet to a liquid outlet. The liquid circuit includes a plurality of spiral liquid passages spiraling radially inward relative to a spray axis. The spiral liquid passages all lie in a plane normal to the spray axis. A manifold assembly includes a plurality of such nozzles. A manifold ring is in fluid communication with the liquid inlet of each of the nozzles to deliver liquid to the nozzles. The nozzles are circumferentially spaced apart around the manifold ring.

In front view of the application nozzle, all of the pressurized air flow K and adhesive flow H are made to run parallel to each other in the vertical direction. Of the pressurized air flows K from the pressurized air hole b in the pressurized air plate, the two that are located on one side of the adhesive hole opening a and from a pair in the front-to-back direction are tilted so as to approach each other. The extension lines thereof are located on the side of the adhesive bead, which results from the adhesive flow discharged from the adhesive hole opening, and have directions that converge. The respective pressurized air flows on the two side of the adhesive bead are made to flow downward while uniting in the direction of convergence. A web in which the adhesive bead is elongated while being swung in the transverse direction is formed and, near the bottom surface of the application nozzle, a non-interference space Q is formed between the adhesive bead and the fore pressurized air flow. The adhesive bead, resulting from the adhesive flow discharged from the adhesive hole opening, and the pressurized air flows do not interfere with each other and walls R of pressurized air flows are formed below the non-interference space Q and on either side of the adhesive bead.

A connecting device for connecting two or more components to one another, includes an inlet section and an outlet section. The inlet section and the outlet section respectively include one or more connectors for each of the two or more components, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic.

A spray wand includes: a hollow tubular main body; a nozzle mounted on the output end of the main body; and a valve assembly configured to mount the input end of the main body. The valve assembly includes: a housing having an input conduit for coupling the valve assembly with a fluid source; a sealing piston biased within the input conduit toward a sealing position thereof; and a valve core having a column rotatable within the interior space of the housing and a handle extending from the column, the valve core being rotatable between at least one open position corresponding to an open condition of the valve assembly and at least one closed position corresponding to a closed condition of the valve assembly. Upon rotation of the column to at least one open position thereof, the sealing piston biased within the input conduit is pressed from the sealing position.

A pneumatic atomizing nozzle (10) which in a preferred form can be supplied with gas by means of a fan (43). The pneumatic atomizing nozzle (10) has a nozzle body (11), which bounds a flow space (21). The pneumatic atomizing nozzle (10) also has a liquid channel (27) having an outlet opening (38). Within the flow space (21), a liquid film (41) is formed, which is transported within the flow space (21) to a nozzle outlet (17) by the gas flow. The outlet opening (38) of the liquid channel (27) defines an outlet direction (A) for the liquid into the flow space (21), which in the preferred embodiment is opposite the flow direction (S) of the liquid film (41). At least in some sections, the liquid channel (27) and the outlet opening (38) extend transversely through the nozzle body (11) in a curved, wound, or meandering manner.
