Abstract: A double-swirl spray nozzle includes two swirl chambers which are connected to a common supply channel which extends in a central plane between the swirl chambers. Both swirl chambers have outlet openings which open outwardly from the supply channel to the same side. The axes of the swirl chambers are furthermore inclined at an angle with respect to one another. Thus with one single compact spray nozzle it is possible to create atomizing cones with a very large impact area which mutually overlap on the side facing one another and in spite of the speed component unidirected in the overlapping area result in a secondary division of the liquid droplets in the two atomizing cones, which increases the efficiency when the nozzle is utilized in so-called gas washers for cleaning purposes.

Abstract: An active compound supply system for a spraying device for spraying liquids, in particular for agricultural purposes, includes a carrier liquid tank, a carrier liquid pump, a plurality of spray nozzles and a carrier liquid line for connecting the carrier liquid tank, the carrier liquid pump and the spray nozzles. The system provides at least one active compound preliminary container, at least one metering pump for feeding active compound into the carrier liquid and an active compound forward-flow line from the active compound preliminary container to the metering pump.

Abstract: A Spraying assembly for spraying liquids for agricultural purposes is provided whose respective sprayer valves attached to a common liquid supply line are at least configured in the form of valve housings whose pair of valve channels share a common distributor bore. This distributor bore allows connecting the bodies of valve housings in one of two positions in order that, provided that they are connected using a t-shaped fitting, they may be arranged either with their valve bores lined up in rows extending to the front or rear of the liquid supply line, as well as ahead of or behind the liquid supply line and aligned parallel thereto. Since one embodiment also provides a rotatable pipe-T joint, the dual-sprayer-nozzle valve units may also be arranged beneath the liquid supply line, which yields a large number of opportunities for laying out the sprayer nozzles, in spite of the simple means available for connecting them.

Abstract: A two-substance spray nozzle includes a mixing chamber in which a target body is provided, against which the liquid stream strikes. The target body is configured as a spreader aligned coaxial with the liquid stream and expanding in the direction of flow up to a spill-over rim, which can be especially conical. The feed passages for the gaseous medium discharge in the direction of flow before the spill-over rim, so that the compressed air delivered can uniformly divide the liquid stream dispersed in the form of a liquid film into fine drops in an effective manner.

Abstract: A method and a mold used with this method for manufacturing cast spray diffusers is described in which, in order to prevent an expensive reworking of important corners and edges, the molded parts are formed is such a way that mold parting planes are moved out of these critical areas. In particular, the transitional area between a rotationally symmetric swirl chamber of a spray diffuser in the narrow mouthpiece channel and the outlet edge of the mouthpiece are each placed in one-piece molded parts that abut against these adjacent molded parts outside these areas.

Abstract: A cooling arrangement for the rolling stand of a continuous casting system for heavy supports is provided with spraying nozzles which can be acted upon by cooling liquid and compressed air through supply pipes laid laterally in a longitudinal direction of the rolling stand. Only two supply pipes for cooling liquid and compressed air respectively are assigned to each side of the rolling stand. The supply pipes are laid parallel to one another and are equipped with connection flanges on which connection plates can be mounted in a simple manner and, in turn, are fixedly connected with spraying nozzles. This further development permits a simple mounting and demounting of the spraying nozzles and ensures a precise alignment of the spraying jets with respect to the billet to be processed.

Abstract: A double-swirl spraying nozzle has two swirl chambers which are open toward opposite sides and are in each case arranged on respective sides of a longitudinal center plane extending through the inflow duct and are preferably designed mirror-symmetrically with respect to the center axis of the inflow duct. This design makes it possible for the medium to enter without any cross-sectional constrictions into the two swirl chambers and to exit with a different swirl in opposite directions.

Abstract: A two-medium spraying nozzle is provided with a mixing chamber arranged in a housing and with one connection duct respectively leading into this mixing chamber for the feeding of a gaseous and of a liquid medium. A mouthpiece is connected behind the mixing chamber, in which mouthpiece a rotationally symmetrical central outlet opening is provided. In the bore of the mouthpiece, a swirl insert is arranged, and the outlet opening has a diameter which corresponds to no more than half the diameter of the bore of the mouthpiece. Such a two-medium spraying nozzle is unsusceptible to clogging and is particularly suitable for atomizing low-viscosity fluids for the cooling of continuous-casting systems for the production of steel.

Abstract: A nozzle for spraying surfaces is equipped with a piston rod centrally arranged in a feeding duct. The piston rod has an impact plate which is held by a spring in a position aligned with the surface to be sprayed. As a result of liquid pressure, the impact plate arrives in a second end position at a distance from the surface to be sprayed in which. As a result of a ring gap on an input side around the piston rod, the impact plate becomes a deflecting part for the spraying liquid exiting in a ring shape, which, in a circular spraying cone directed at a flat angle with respect to the surface to be sprayed, is then emitted onto the surface to be sprayed.

Abstract: Known high-pressure spray nozzles tend to develop wear at outlet edges for a flat stream because of fluid emerging at very high pressure. It has already been proposed to provide, on the nozzle bodies, instead of transverse continuous outwardly open groove-shaped cuts, outlet channels with a cross-sectional pattern that expands outward trumpetwise in an elliptical shape or to prevent any contact between the nozzle body and the high-pressure stream at the outlet edge. It is now proposed to provide the outlet channel with an elliptical cross section, with expansion of the cross section exclusively in the direction of the major semiaxis but with no increase in dimension in the direction of the minor semiaxis. In this way, the flat stream to be formed can be guided and held together without wear at an outlet edge. The nozzle can be used as a high-pressure flat stream nozzle for de-scaling.

Double spin spray nozzles can be used that produce oppositely aimed spray jets of different spin.

Abstract: A flat-jet nozzle for atomizing liquids into comparatively large drops and comprising a nozzle housing with an axial feed passing through it with a multiple stepped diameter, this feed being provided at its end with a nozzle discharge slit. Moreover an inset with a central throttling bore is mounted in the liquid feed between the liquid intake and the discharge slit. A cylindrical central zone of a larger diameter than the discharge slit is present in the liquid feed in the nozzle housing. The inset is provided with a deflector through which the liquid jet issuing from the throttling bore into the central zone is forced, preferably bilaterally, toward the large axis of the nozzle discharge slit.

Abstract: A binary atomizing flat-jet nozzle with rectangle characteristic comprises a mixing head forming a mixing chamber with two mutually orthogonal connectors for a gaseous and a liquid medium, further a preferably tubular connector connecting to those connectors and a snout forming the slitted nozzle discharge. A metering inset with a cylindrical blind bore is mounted in the second connector supplying the liquid, the blind bore issuing inside the mixing chamber bilaterally into cross-bores. The snout comprises an offset bore with arched bottom. A baffle with a sharp-edged central transmission aperture rests on the bore offset and comprises an inside diameter less than the diameter of the offset snout bore. A nozzle with the above features is characterized by its simple design, easy manufacture and very uniform liquid distribution (so-called rectangle characteristic).

Abstract: A nozzle for atomizing liquid media, in particular a fan-jet nozzle, comprising a nozzle housing determining by its external dimensions and its fitting means the particular nozzle type, and a nozzle internal structure enclosed by the nozzle housing in turn determining the nozzle type functionally, both the nozzle housing and the nozzle inner structure being made of the same material. The nozzle housing on one hand and on the other the nozzle inner structure (nozzle inset) are separate integral parts, and the nozzle inset is force-fitted in undetachable manner into the nozzle housing. Such separate manufacture of the nozzle housing on one hand and on the other the nozzle inset determining the nozzle inner geometry (functional geometry) allows improving applicability and storage costs while simultaneously lowering the manufacturing and storage costs of said nozzle.

Abstract: A two-material atomizing nozzle to produce a solid cone jet with a jet angle larger than 45.degree. comprises a nozzle unit with a first duct coaxial with the nozzle discharge and receiving a gaseous medium (for instance air) and a liquid medium (for instance water), a second duct orthogonal to the first duct and issuing into it serving to supply the liquid medium. To supply the gaseous medium, the nozzle unit comprises a third duct issuing into the first duct at the level of the second duct and being orthogonal or essentially orthogonal to both. A recoil bottom is provided for the premixed two-material mixture in the first duct and comprises communication apertures to an annular duct coaxial with and preceding the nozzle discharge into which it merges. The nozzle discharge also is in the shape of an annular duct, however its external boundary is flaring.

Abstract: An ultrasonic atomizer for liquids comprises a piezoelectric transducer (16) mechanically coupled to an amplitude transformer (20), an atomizing disk (21) mounted to the free end of the amplitude transformer (20), a housing (22) enclosing at least the amplitude transformer (20) and a cap (30) supporting a sieve-like diaphragm (31). The cap (30) is so mounted to the housing (22) that the diaphragm (31) rests on the atomizing disk (21). The cap (30) consists of two mutually concentric cap parts (32, 33) of which one (32) supports the diaphragm (31) and the second (33) serves to mount the entire cap (30) on the housing (22). A spring (36) is so mounted between the two cap parts (32, 33) that the sieve-like diaphragm (31) is held elastically against the atomizing disk (21) and that the opposing force from the spring (36) thereby is transmitted into the second cap part (33) fixed in the housing.

Abstract: A cylindrical inset forming a mixing chamber in a binary atomizing nozzle is mounted in a housing ahead of the nozzle discharge and is provided with radial boreholes. The liquid to be atomized, for instance water, and the atomizing gas, for instance air, are fed to the cylindrical inset, with the liquid arriving axially and the gas passing radially from an annular spacing surrounding the inset within the nozzle housing through the radial boreholes into the inset. The radial boreholes are located in several consecutive transverse plans when viewed in the direction of flow and are arrayed in mutually offset manner in the circumferential direction of the cylindrical inset.
