    The invention relates to a connection or feedthrough element for a pipe, in particular an exhaust pipe, on or through a wall, in particular a wall of a sound-insulating housing.
    From DE 32 09 306 Al a pipe feedthrough is known in which a pipe passes through a sealing wall opening. Between the wall and the pipe, a sleeve is provided, which is held tension-free. It consists of a cylindrical portion of approximately the same diameter, as the tube outer diameter and a subsequent frusto-conical portion which is fixed by means of an annular flange on the wall. The support function of the pipe takes over a specially attached and attached to the ground shell, opposite which the tube is displaceable. However, vibrations can be transmitted to the soil via the shell.
    When carrying out an exhaust pipe of an internal combustion engine through a schaliabsorbierendes housing, there is the problem that the exhaust pipe must be passed through the sound-absorbing housing vibratory, without vibrations are introduced into the housing. However, an air gap between the exhaust pipe and the housing is associated with acoustic disadvantages.
    The object of the invention is to avoid these disadvantages and to provide a connection or feedthrough element for connecting a pipe to a container, which on the one hand seals the tube against the interior of the container and on the other hand compensates for vibrations and thermal expansions between the pipe and container.
    According to the invention this is achieved in that between at least one preferably substantially annular first flange and at least one preferably substantially annular second flange at least one flexible, preferably elastic membrane is formed, wherein preferably the first flange concentric to the second flange, in particular within the second flange is arranged.
    In an advantageous first embodiment, it is provided that - in the relaxed state - the diaphragm is flat, the first flange and the second flange being arranged essentially in the same plane, preferably in the diaphragm plane or in a plane parallel to the diaphragm plane. - 2 -
    Due to the flat design of the membrane and the flanges space is saved on the one hand in the axial direction and on the other hand does not hinder the free movement of the tube formed for example by an exhaust pipe relative to the container. The exhaust pipe can thus oscillate both axially and radially within the connection and feedthrough element, without transmitting the movements in the container.
    In order to enable a fixed connection of the connecting and feedthrough element to the container on the one hand and on the other hand to the tube, it can be provided that the first and / or second flange is formed by a rigid and / or dimensionally stable ring, preferably made of metal. For attachment to the pipe or to the container, the first and / or the second flange may each have at least one mounting hole.
    The number of parts can be reduced if the second flange is formed by at least one pipe flange of the pipe, wherein preferably the membrane between two axially fixedly connected, preferably clamped together pipe flanges is clamped.
    A particularly good acoustic decoupling between the pipe and the wall can be achieved if the membrane has at least one, preferably circumferential, folding between the first and the second flange.
    The membrane may be made of a flexible and / or elastic material, for example made of temperature-resistant plastic, a coated fabric or metal.
    The invention will be explained in more detail below with reference to FIG.
    1 shows a connection and feedthrough element according to the invention in an exploded view in a first embodiment, FIG. 2 shows a connection and feedthrough element according to the invention in a second embodiment in a section normal to the plane of the membrane, FIG. 3 shows a connection and feedthrough element according to the invention a third embodiment variant in a section normal to the diaphragm plane, Fig. 4, the connection and feedthrough element of FIG. 3 in a deflection position and Fig. 5, the connection and feedthrough element of FIG. 3 in a further deflection position.
    Fig. 1 shows an exploded view of a Erfrndungsgemäßes connection or feedthrough element 1 for connecting a pipe formed by an exhaust pipe 2 to the wall 3 of a sound-absorbing housing 30 of an internal combustion engine, not shown, for example, a power - 3 - aggregate. The connecting or feedthrough element 1 has in this embodiment at least one inner first flange 4 and at least one outer second flange 5, wherein the flanges 4, 5 are formed substantially annular. Between the inner and outer flanges 4, 5, a membrane 6 made of a flexible and / or elastic material, for example made of high temperature resistant plastic, a coated fabric or metal is clamped. The first and second flanges 4, 5 are formed by rigid and / or dimensionally stable rings, for example made of metal, wherein in the flanges 4, 5 each mounting holes 7, 8 with the axes 7 ', 8' for attachment of the exhaust pipe 2 at the terminal - or feedthrough element 1 on the one hand and for attachment of the connection or feedthrough element 1 on the container 3 on the other hand are provided.
    The connection and feed-through element 1 is formed flat, wherein the concentrically arranged flanges 4, 5 are formed substantially in a plane parallel to the diaphragm plane ε arranged. As a result, the size of the housing 30 in the axial direction of the exhaust pipe 2 is not adversely affected. On the other hand, the design of the connecting and feedthrough element 1 allows the compensation of axial and radial vibrations between the exhaust pipe 2 and the housing 30, so that vibrations of the exhaust pipe 2 are not introduced into the housing 30. The membrane 6, which may also be gas-tight, causes an acoustic seal of the interior of the housing 30 from the environment.
    The simplified in Fig. 1 with adjoining pipe flanges 2a, 2b drawn exhaust pipe 2 is attached with its pipe flanges 2a, 2b on the first flange 4 of the connection and feedthrough element 1 with screws 2c so that the connection and feedthrough element 1 between the pipe flanges 2a, 2b is arranged. Furthermore, the connection and feedthrough element 1 is fastened by means of the second flange 5 to a connection surface 3a on the outer surface of the wall 3 of the housing 30 by means of further screws not shown.
    The connection and feedthrough element 1 is thus firmly connected both to the housing 30 and to the exhaust pipe 2. By the flexible and / or elastic membrane 6 vibrations and thermal expansion can be compensated without causing an acoustically unfavorable gap between the housing 3 and the exhaust pipe 2.
    Fig. 2 shows an embodiment in which the membrane 6 is clamped directly between the pipe flanges 2 a, 2 b of the exhaust pipe 2. The second flange 5 is formed in this case by the two pipe flanges 2 a, 2 b of the exhaust pipe 2, which may be firmly connected to the exhaust pipe 2, for example, welded.
    In Figs. 1 and 2, the membrane 6 is formed in the relaxed state substantially completely flat, whereby an acoustic decoupling between the exhaust pipes 2 and the housing 30 succeeds when using flexible and elastic materials. In order to be able to use less elastic materials, for example of metal, for example made of sheet steel, the membrane 6 may have at least one bellows-like circumferential fold 9 between the first and the second flange 4, 5, as shown in FIG. As a result, relative movements between the first and second flange 4, 5 both in the direction of the tube axis 2 '(FIG. 4), as well as transversely thereto (FIG. 5), as well as pipe inclinations, are possible.
