    Annular sealing ring between two ducts, in particular for the building.
    The present invention relates to the field of sealing rings between ducts, one of which is engaged in the other, for the flow of fluids.
    In particular, the present invention relates to the field of vertical ducts passing through walls of buildings such as roofs or roof terraces, including ventilation ducts.
    Currently, the bushings, which overflow above the wall, are sealed by the fact that the sealing of the top of the wall is extended upwards around and against the ducts, this sealing being further reduced to inside the upper part of the ducts. Because the bushings are cylindrical and the seal must make a 90 degree fold at the foot of the conduit and a 180 degree fold at the top of the conduit, such a procedure is complicated and requires special attention. It is consequently expensive and risks of defects are possible, even unavoidable.
    Furthermore, a sealing device is known between an outer pipe and an inner pipe, described in patent EP 2 636 913, which comprises an inner ring sliding inside an outer pipe and an annular seal interposed between one end. the inner duct and the inner ring, this seal also coming into contact against the wall of the outer duct.
    According to one embodiment, there is provided a sealing ring which comprises an annular body having a central flow passage.
    Said body is provided with at least first and second annular outer sealing portions, radially outwardly projecting and spaced axially from each other.
    Said body has an annular axial bearing face and an annular deflection face, axially opposite, said first annular sealing portion being adjacent to said annular axial bearing face, said second annular sealing portion being adjacent to said face deflection means, said annular deflection face extending between an outer annular edge of said second annular sealing portion and said central passage and being adapted to deflect a flow towards said central passage.
    Said annular sealing portion adjacent to said axial bearing face may be in the form of a bead.
    Said annular sealing portion adjacent to said deflection face may be in the form of a lip.
    Said annular deflection face may be substantially in the form of a conical truncated cone towards said flow passage.
    Said body may be provided with at least one outer annular sealing portion located between and away from said annular outer sealing portions.
    Said body may be provided with an inner annular portion axially projecting from said annular axial bearing face, opposite said deflection face, said inner annular portion at least partially providing said central passage.
    Said inner annular portion may be provided with an annular flange radially outwardly projecting.
    Said annular deflection face can form a flashing.
    There is also provided an assembly that includes an outer conduit and an inner conduit having one end located within the outer conduit and that includes a seal ring.
    In this assembly, said annular sealing portions of said sealing ring are in contact against the inner wall of the outer conduit and said axial bearing face of said sealing ring abuts against the end of the inner conduit.
    According to a particular application, said inner duct may be a vertical duct passing through a wall of a building such as a roof or a roof terrace, said outer duct may be a tube disposed around the passage duct and fixed on said wall in a position such that it has an end portion extending upwardly beyond the upper end of the passage duct, said annular axial bearing face of said sealing ring being directed towards the bottom and bearing on the upper end of the vertical passage conduit and said annular deflection face of said sealing ring being oriented upwards.
    A sealing ring and a particular application of such a ring will now be described as non-limiting examples, illustrated by the drawing in which: - Figure 1 shows a section of a sealing ring, included in an assembly comprising an outer conduit and an inner conduit; and - Figure 2 shows a vertical section of a particular assembly for a wall of a building.
    As illustrated in FIG. 1, an assembly 1 comprises an annular sealing ring 2 intended to form a seal between an inner duct 3 engaged axially in an outer duct 4, with a clearance or radial space between them, one end 5, cut off right, being inside the outer conduit 4. For example, the ducts 3 and 4 are cylindrical.
    The sealing ring 2, which is generally cylindrical, for example, comprises an annular body 6 which has a central flow passage 7.
    The annular body 6 has an annular axial bearing face 8, and an annular deflection face 9, axially opposite to the annular support face 8.
    The annular body 6 is provided with a first outer annular sealing portion 10 and a second outer annular sealing portion 11, radially outwardly projecting with respect to an outer annular face 12 of the annular body 6 and axially distant from each other.
    The first annular sealing portion 10 is adjacent to the annular support face 8 and the second annular sealing portion 11 is adjacent to the annular deflection face 9.
    The annular deflection face 9, which extends between the outer annular edge of the second annular sealing portion 11 and the central passage 7, forms a deflection flashing which deflects a flow reaching the annular deflection face 9 towards the passage central 7.
    The annular body 6 may be further provided, for example, with two intermediate annular outer sealing portions 13 and 14, located between and away from the outer annular sealing portions 10 and 11 and projecting from the outer face 12.
    In a particular configuration illustrated in FIG. 1, the annular axial support face 8 extends radially, the annular deflection face 9 is in the form of a conical frustum converging towards the central passage 7 and the annular face. 12 is cylindrical, so that the axial section of the annular body 6 is substantially triangular.
    The annular sealing portion 10 is in the form of a bead substantially of semicircular section.
    The annular sealing portion 11 is in the form of an inclined lip whose thickness is reduced from the inside to the outside.
    The intermediate annular sealing portions 13 and 14 are in the form of lips.
    The annular body 6 is provided with an inner annular portion 15 axially projecting from the annular support face 8, opposite the annular deflection face 9. This inner annular portion 15 arranges the central passage 7.
    The inner annular portion 15 is provided with an annular flange 16 radially outwardly projecting, extending opposite and axially remote from the annular support face 8.
    As illustrated in FIG. 1, the sealing ring 2 is coupled to the ducts 3 and 4 in the following manner.
    The sealing ring 2 is engaged axially, by sliding, inside the outer conduit 4.
    The outer annular ends of the annular sealing portions 10, 11, 13 and 14 are in contact with the inner wall of the outer conduit 4.
    The annular support face 8 is in contact against the annular end 5 of the inner conduit 3.
    The annular portion 15 is engaged at a radial distance inside the inner conduit 3 with a radial clearance. The inner annular end of the annular flange 16 is in contact against the inner wall of the inner duct 3.
    Advantageously, the end 5 of the inner duct 3 enters the annular face 8 of the sealing ring 2, so that the annular sealing portion 10 partially engages between the ducts 3 and 4.
    Annular chambers are formed axially between the annular sealing portions 10, 11, 13 and 14 and radially between the cylindrical wall 12 and the inner wall of the outer duct 4.
    A chamber is also formed axially between the annular support face 8 and the collar 16 and radially between the inner wall 15 and the inner wall of the inner conduit 3.
    This creates a seal between the inner duct 3 and the outer duct 4, isolating the space 17 between the ducts 3 and 4, vis-à-vis, with respect to the interior of the inner duct 3 and the portion of the external duct 4 not covered by the inner duct 3 and up to the sealing ring 2.
    The annular deflection face 9 extends from the inner wall of the outer conduit 4, by contact of the outer end of the annular sealing portion 11 against this wall, towards the central passage 7. The annular deflection face 9 is thus able to deflect a flow arriving through the outer conduit 4 to the central passage 7 and thus to the inner conduit 3, a rise towards the annular support face 8 being blocked by the annular wall 15 and the annular collar 16.
    The frictional contact of the annular sealing portions 10, 11, 13 and 14 against the inner wall of the duct 4 keeps the annular support face 8 in sealing contact against the end 5 of the inner duct 3.
    Before the introduction of the sealing ring 2 inside the outer pipe 4, the outer diameters of the annular sealing portions 10, 11, 13 and 14 are greater than the inner diameter of the outer pipe 4 and the inner diameter of the flange 16 is greater than the outside diameter of the inner duct 3.
    The annular sealing ring 2 can be obtained by molding.
    The annular sealing ring 2 can also be obtained by extrusion through a die of a profile whose section corresponds to its axial section, cutting a portion of this profile, and then winding and welding the ends of this portion . Under these conditions, the annular body 6 may have an inner annular channel 18.
    The sealing ring 2 may be in one or different rubbery materials or in one or more special elastomers such as EPDMs.
    FIG. 2 illustrates an example of application of the assembly 1 provided with the sealing ring 2 described with reference to FIG.
    In this figure 2 is shown a wall 101 of a building, such as a roof or a roof terrace, in particular a slab on which are placed an insulator 102 and an upper seal 103.
    The wall 101 is equipped with a cylindrical passage duct 104 installed vertically in a hole 105 of the wall 101 and which passes through the insulator 102 and the upper seal 103, so that the duct 104 has an end portion superior which extends to the outside. The cylindrical passage duct 104 is for example a ventilation duct.
    A cylindrical tube 106 is arranged vertically, with a clearance, around the duct 104. The lower end of the tube 106 is fixed to the wall 101. In one example, the lower end of the tube 106 carries an annular flange 107 integrated with In another example, the lower end of the tube 106 may be provided with a flexible membrane, according to the European Patent No. 1,710,365, integrated in the seal 103.
    The tube 106 has a length such that it extends upwards beyond the upper end of the duct 104.
    The duct 104 and the tube 106 are equivalent to the ducts 3 and 4 of the assembly 1 described with reference to FIG.
    The conduit 104 and the tube 106 are equipped with an annular sealing ring 108 equivalent to the annular sealing ring 2 of the assembly 1 described with reference to Figure 1 and installed in an equivalent manner. Below, aforementioned references of the annular sealing ring 2 will be repeated about the annular sealing ring 108.
    An operator engages the annular sealing ring 108 in the tube 106 by the upper end of this tube 106, its annular support surface 8 being oriented downwards and its annular deflection face 9 is oriented upwards. The operator pushes the annular sealing ring 108 downwards, the annular sealing portions 10, 11, 13 and 14 sliding against the inner wall of the tube 106, until its annular support surface 8 reaches and bears against the upper end of the duct 104, the annular portion being engaged radially within the interior duct 3 with a radial clearance and the inner annular end of the annular collar being in contact with the inner wall of the conduit 104.
    The annular sealing ring 108 is put in place and a seal is ensured between the duct 104 and the tube 106.
    After which, the operator installs a cap 109 at a distance from the upper end of the tube 106, this cap 109 being provided with tabs 110 whose lower ends are connected to the upper end of the tube 106, for example by staples 111.
    If a liquid such as rainwater, dust or snow enters the tube 106 from its upper end, these materials are deflected by the annular sealing ring 109 inwardly of the conduit 104 and are prevented from penetrating between the duct 104 and the tube 106, reaching the seal 103 and the wall 101 and flowing around the passage duct 104 through the wall 101.
    The sealing ring 2 may have other applications, especially in the field of water flows, especially rainwater flows.
