    The invention relates to a device for conditioning fluids in a housing with a vortex generator that forms a guide device for the fluid between an inlet and an outlet.
    Such a device for conditioning fluids before subsequent combustion is disclosed, for example, in AT 413 875 B, according to which the vortex generator induces a helical flow to the fluid and thus generates a vortex, the flow cross section through the vortex generator being equal to or greater than that through the inlet - and process. However, this flow cross-section ratio is not necessarily advantageous for conditioning, in particular it has been found that said vortex generators ensure thorough mixing of the fluid, in particular a fuel, but do not bring about the desired conditioning.
    For the conditioning of gases before subsequent combustion, it is known (US Pat. No. 3,955,835) to use a swirl generator in the line shortly before a burner, which has several gears of a steep thread in corresponding grooves. The flow cross-section is significantly reduced compared to the inlet and outlet and in the outlet area, in continuation of the thread grooves mentioned, a flow profile is generated from sub-streams that continue to turn in a screw-like manner.
    Another possibility of fuel conditioning is shown in DE 41 19 081, according to the teaching of which a turbine is provided which is supplied with fuel via a tangential inlet, which is subsequently derived via a concentric outlet and is used for further use. The fuel is mixed thoroughly.
    2.15
    The invention is therefore based on the object of specifying a device of the type described at the outset which enables improved conditioning of fluids, in particular of fuels, such as vegetable oils, mineral oils and gases.
    The invention achieves the stated object in that the vortex generator comprises a guide body having a rotation surface generated by a curve rotating about an axis, into which a counter-directed guide insert is inserted, which at least partially abuts the rotation surface, at least between the guide body and the guide insert a helical around the axis in Fördemchtung around current flow channel for the fluid is provided.
    With such a device, the desired improved conditioning of fluids, in particular of fuels such as vegetable oils, mineral oils and gases, is possible because the fluid with the vortex generator according to the invention can be forced to exert particularly high internal shear forces which bring about the desired conditioning effect. Surprisingly, it has been shown that fuels prepared in this way burn more effectively and cleanly before combustion, which not only improves the exhaust gas behavior, but also can reduce the fuel consumption with the same output.
    The mechanical, helical guidance of the fluid around the axis in the conveying direction brings about an acceleration of the fluid to a tip of the guide insert, the exit from the vortex generator, the fluid being compressed. At the top, the fluid dissolves in a vortex and is subsequently fed to the drain. Through this process, the proportions of long hydrocarbon chains in particular are advantageously conditioned and any oxygen components dissolved in the fuel are oxidized with non-combustible substances. This subsequently leads to improved combustion and thus also a higher efficiency.
    Depending on the required flow rate or also depending on the viscosity of the fuel, it is advantageous if at least two, preferably several
    3/15 are provided helically around the axis in the conveying direction around running flow channels for the fluid. The flow channels thus run around the axis in the manner of a multi-start thread, the individual channels emerging from the vortex generator in the area of the tip of the guide insert and the desired conditioning effect being additionally reinforced. The choice of the number and the dimensioning of the flow channels is the responsibility of the person skilled in the art and naturally depends on the intended use and the flow rate.
    Simple design relationships result when the flow channel has a semicircular cross section. The flow channel or the flow channels can thus advantageously be manufactured. In addition, if there is a corresponding flow through the flow channel, additional shear forces arise due to the geometry.
    The flow channel is preferably formed by a groove which springs back into the guide insert from a guide insert envelope surface, the guide insert envelope surface abutting the rotational surface. The flow channels are therefore worked into the surface of the guide insert and are closed to the extent that the guide insert inserted into the guide body, with the exception of the areas penetrated by grooves, rests over the entire surface of the rotating surface of the guide body. Alternatively or additionally, the flow channel can be formed by a groove which springs back into the guide body from the surface of rotation. The flow channel is then closed by the guide body.
    In order to ensure a defined fluid flow through the flow channel, the guide insert can be pressed against the guide body with a clamping device, whereby any leakage currents, for example between adjacent flow channels, can be avoided.
    Effective conditioning conditions result when the curve rotating around the axis is an arc and the generated surface of revolution is a partial surface of a torus. The flow channel runs in particular along a channel line according to the formula
    4/15 / S X (R, Φ) / cos (-0 + t2 R )
    S (R, φ): = S y (R, ¢) = sin <-0 + t2 R )
    VW, ¢) / ßsin (v) / around the axis.
    The guide body and / or guide insert preferably consist of aluminum, in particular an aluminum alloy, at least in the region of the flow channel, with which the conditioning of fluids can be improved due to catalytic effects.
    The subject matter of the invention is shown in the drawing, for example. Show it

    The device for conditioning fluids in a housing 1 comprises a guide device for the fluid-forming vortex generator 2 between an inlet 3 and an outlet 4.
    The vortex generator 2 has a guide body 8, which has a rotating surface 7 generated by a curve 6 rotating about an axis 5 and in which a guide insert 9 of the same type is inserted. The guide insert 9 lies at least partially on the rotation surface 7, wherein at least one flow channel 11 for the fluid, which extends helically around the axis 5 in the conveying direction 10, is provided between the guide body 8 and the guide insert 9.
    The guide insert 9 has a plurality of flow channels 11 for the fluid which run helically around the axis 5 in the conveying direction 10 and each have a semicircular shape

    The guide insert 9 is pressed against the guide body 8 with a clamping device 12, a clamping screw guided in the housing 1. The housing 1 comprises a base body, into which the vortex generator 2 is inserted, and a housing cover, which accommodates the inlet 3 and the outlet 4, and can be removed from the base body.
    The curve 6 rotating about the axis 5 is an arc and the generated rotating surface 7 is a partial surface of a torus.
    The geometry of the flow channel along a channel line S of the vortex generator 2 is described below, the channel line S lying in the surface of rotation.
    The 3-dimensional channel line S consists of the following three x, y and z components in the Cartesian system:
    S x (R, fi) = r (</>) cos (—φ + t2n) (1)
    S y (R, φ) = r (</>) sin (—φ + ΐ2π) (2)
    5 Z (7 , 0) = 7 Sinl ^ l (3)
    A single channel line S (R, φ) is completely described with equations 1, 2 and 3. In vector form, the equation is as follows:
    / S x (/ , 0) £ (/ , </>): = S y (/ , </>) W) / r (</>) cos (—φ + t2n)
    Γ ^ φ) sin (—φ + ΐ2π)
    R sin - 4 (4)
    The radial function (5) in gig. 4 describes the increase in radius due to the screw geometry.
    r (/ , φ) - Oß + 0 $ + R · - cos (5)
    6/15 where R corresponds to the radius of curve 6 and φ [0.2π] the polar angle. A complete turn corresponds to covering the entire channel line against the
    Clockwise. If the direction of rotation of the screw is to be reversed, the interval [0, -2π] must be used instead.

    Dmz 2 * π
    Amz = ------------------ [mm 2 ] (6)
    The cross-sectional area Ak of each semicircular flow channel 11 is calculated
