    The invention is a multiorifice structure and method of manufacture. The structure comprises a plurality of triangularly shaped orifices angularly disposed with respect to a common axis. The structure is formed by fusing together concentric alternating layers of cylindrical members and parallel rods angularly disposed with respect to the axis of the cylindrical members. The fused structure is sliced generally normal to its axis to produce a plurality of multiorifice wafers or discs. The interstices between the rods and the cylindrical members form a plurality of small triangularly shaped orifices particularly well suited to use as an atomizer for an internal combustion engine fuel injector valve.

    (54) SPRAY ELEMENT WITH A VARIETY OF HOLES AND METHOD OF HIS PRODUCTION
    During the laying of the rods on the shells, the rods are twisted so that they form an acute angle with the longitudinal axis of the sheath.
    Moreover, the rods of each subsequent row, as they are removed from the longitudinal axis of the shells, are twisted through a larger angle relative to this longitudinal axis than the rods of the previous row. „: -, - .- .., .- :. . -, - The rods are coated with a layer of material gum lower melting temperature than the material of the rods and shells, while the block is heated to a temperature lower than the melting temperature of the rods and shells and higher melting temperature of the coating material.

    The dilution element (Fig. 1) is a plate consisting of an interleaved concentric row of dBV rods 1 and cylindrical shells 2. Each row of separate cores and 2 n ak lneny refers to a single prod to;
    Each row of rods 1 with distance from the center of the spray element is located at a large angle relative to the central rod 3, the previous row (Fig. 2). The spray element may contain from two to three rows of rods up to 100 or more. The angles of inclination of the rods may have values that are different from those of FIG. 2. Increasing the inclination of the grain leads to an increase in the dispersing ability of the spray element.

    The operation of the spray element is as follows.
    The liquid is supplied through the holes 4 of the plate, in which case a splitting of the liquid structure occurs and its spraying. The triangular shape of the holes leads to more effective spraying of the liquid than the round form. It is known that the surface tension forces acting on the ejected fluid cause the fluid flow to fluctuate; the liquid jet breaks into small droplets. Triangular holes result in the formation of large surface tension forces acting on the ejected liquid, which, in turn, leads to the formation of smaller droplets of liquid than when the liquid flows through round holes. In addition, the triangular holes have the same size, so that the resulting liquid droplets also have the same size ..
    FIG. 4, 5, b illustrate the method of fabrication of the spray agent. In the spray element, shown in FIG. 4, the center pivot; s is surrounded by six or more rods; and whether wires. The rods in the first row are twisted around the central rod at an angle ot equal to 5. The central rod and the twisted rods covering it are nested in a cylindrical shell 5, while the rods 6 are in contact with the shell. Then, the next row of rods 7 are laid on the shell 5. Their outer surfaces are in contact with each other. The second layer of rods 7 are twisted around the outer surface of the cylindrical shell 5. The twisted rods 7 are inclined relative to the central rod by an angle, which may be equal to the angle ". or more and compose it, e.g. Vlsh, formed z1y from one shell 5 and two p d of rods 6 and 7 put into a cylindrical shell 8 ..
    Next, the next row of rods 9 are laid in the same way. The outer shell shells are chosen so that they have an integer number of rods on them.
    The number of stacked rows of rods and shells is determined by the given diameter of the spray element. The resulting blrk. then fused. Each rod is fused with adjacent rods and with shells.

    Claims (11)
    [1]
    In order to facilitate the fusion of the rods and cylindrical rbols, they are covered with a three-layer layer of material having a lower melting point than the melting point of the material of the rods and shells (Fig. 5). Rods and bowls can be made of, for example, stainless or carbon steel, and copper, nickel or other material having a lower T & t melting point can be used as a covering material. Glass and plastic may also be used to make the release member. In addition, it is not always necessary to turn both rods and shells, for example, only shells or rods can be covered. The fused block is then cut (FIG. B) into separate plates of the required thickness. The surface of the plates along the section can be merged or polished. The proposed dust element is reliable in operation and provides high quality spray. . Claim 1.
