    According to an embodiment of the connecting piece, said flange portion is arranged inside and outside of said sleeve portion. This facilitates the connection of pipe sections with different diameters.
    According to an embodiment of the connecting piece, said flange portion is arranged substantially centrally in the axial direction of said sleeve portion. This facilitates good sealing independent of axial movement of the connecting piece relative to the pipe pieces.
    According to circumferentially arranged at said sleeve portion. This enables an embodiment of the connecting piece, said flange portion being a simple construction of the connecting piece.
    According to an embodiment of the connecting piece, said flange portion comprises resilient portions against which said end surfaces are arranged to act.
    As a result, a joint is obtained which results in reduced impact when the pipe sections collide with the flange portion and consequently reduced wear. According to one embodiment, the connecting piece comprises sealing means arranged to act sealingly against said pipe pieces. This results in an effective seal.
    According to a connecting piece, said sealing means comprises O-ring elements of said sleeve portion. This enables effective sealing. embodiment of According to a connecting piece, said sealing means comprises by vulcanization applied elements of said embodiment of sleeve portion. This enables effective sealing. Furthermore, it is possible to use a circular-cylindrical sleeve portion without changes externally or internally in diameter in the form of grooves and / or projections, said elements applied by vulcanization also comprising said flange portion with resilient properties for said action by means of the end surfaces of the pipe pieces.

The first sealing element 632 is arranged to seal against the first pipe piece 10 in the assembled state. The second sealing element 634 is arranged to seal against the second pipe piece 20 in the assembled state. The first sealing element 632 consists of a circumferential leaky bulging projection 632 of the first element 630a and the second sealing element 634 is constituted by a circumferential inwardly bulging projection 634 of the second element 630b.
    Connector 500; 600 according to the fifth and sixth embodiments in Figs. 5 and 6 facilitates the connection of pipe sections 10, 20 of different diameters, without affecting the geometry of the end area of the respective pipe section 10, 20.
    Flange portion 110; 210; 310; 410; 510a, b; 610a, b according to the above embodiments are arranged to guide the connecting piece 100 during assembly; 200; 300; 400; 500; 600 axially in that the respective end surfaces 12, 22 of the first and second pipe sections 10, 20 are arranged to act against the flange portion 110; 210; 310; 410; 510; 610. When the connecting piece is arranged between the pipe pieces 10, 20, their respective end surfaces 12, 22 will act against the flange portion 110; 10 15 20 19 210; 310; 410; 51 Oa, b; 610a, b which in this way functions as axial control of the pipe pieces 10, 20. Thus no adjustment of the pipe end pieces 10, 20 and end portions 12, 22, respectively, is needed. 210; 310; 410; 510a, b; 610a, b may also be formed with resilient portions in the form of sealing means 132, 134; 232, 234; 332, 334; 442, 444; 532, 534; 632, 634 which can absorb forces caused by mutual movement between the pipe pieces 10, 20 and reduce the wear on their respective end surfaces 12, 22.
    Connector 100; 200; 300; 400; 500; 600 according to the above embodiments can be used to connect any suitable pipe fittings in any suitable application. Said connecting piece is, for example, applicable for connecting pipe sections in so-called EGR circuits in vehicles, coolant circuits, air circuits or the like. Said sleeve portion 120; 220; 320; 420; 520; 620 is according to one embodiment made of a metallic material.
    The above description of the preferred embodiments of the present invention has been provided for illustrative and descriptive purposes. It is not intended to be exhaustive or to limit the invention to the variations described. Obviously, many modifications and variations will occur to those skilled in the art. The embodiments have been selected and described to best explain the principles of the invention and its practical applications, thereby enabling one skilled in the art to understand the invention for various embodiments and with the various modifications appropriate to the intended use.
