Definitions

  • the invention relates to a sealing arrangement for an exhaust gas cooler according to the preamble of claim 1.
  • a flat seal is clamped between a flat connection element and a flat sealing element, whereby a gas-conducting connection point between the connection element and the sealing element of an exhaust gas cooler is sealed.
  • the seal essentially corresponds to the contour of the connection element and of the sealing element, so that a gas passage between the connection element and the sealing element and screw openings for fixing the connection element remain open on the sealing element. A displacement of the seal relative to the connection element or to the sealing element leads to an undesirable leakage and should be avoided.
  • the object of the invention is therefore to provide a sealing arrangement for an exhaust gas cooler, in which the mentioned disadvantages are overcome.
  • a seal assembly for an exhaust gas cooler has a plate-shaped connection body and a surface seal, which bears against a sealing surface of the connection body.
  • the connection body has a gas guide passage penetrating the connection body, which corresponds to a gas guide opening in the surface seal.
  • the connection body has at least two fixing holes, which correspond with corresponding fixing openings of the surface seal.
  • the surface seal has at the respective Festlegö réelleen in each case an integrally formed on the surface seal clamp assembly which engages in the respective Festlegbohrung the connector body.
  • the respective fixing bore has on an inner circumference a first form-fitting contour and the respective clamping arrangement has a second form-fitting contour which forms a positive fit.
  • the surface seal fixed in a form-fitting manner to the connection body and fitting to the sealing surface. Due to the positive connection, the surface seal is fixed axially to a longitudinal axis of the respective fixing hole, so that a displacement of the surface seal perpendicular to the sealing surface and thus a release of the surface seal are avoided by the connection body. Characterized in that the surface seal is fixed positively to the at least two fixing holes, the surface seal is also determined to be non-displaceable radially to the respective longitudinal axes and on the sealing surface. Furthermore, this also avoids a twisting of the surface seal on the connection body relative to the respective longitudinal axes.
  • both an undesired release of the surface seal from the connection body and an undesired displacement or rotation of the surface seal on the sealing surface can be avoided in the seal arrangement according to the invention.
  • the transport and assembly of the seal assembly are thereby considerably simplified and further enables a secure sealing.
  • the first form-fitting contour is formed by at least one step-like recess facing away from the sealing surface in the respective fixing hole and the clip arrangement is formed by at least one tab engaging at least in certain areas in the step-like recess and having the second positive-locking contour.
  • the at least one step-like recess and the at least one tab suitably form a positive connection, so that the surface seal is fixed to the connection body axially to the longitudinal axis of the respective fixing hole.
  • both a single tab and a plurality of tabs can be arranged in a form-fitting manner.
  • the at least one step-like recess extends axially in the fixing hole and the at least one tab is arranged completely within the fixing hole. To this This reduces the risk of injury to the tab during assembly of the seal assembly and also simplifies the assembly of the seal assembly.
  • the inner circumference of the respective Festlegbohrung is partially formed by a circular bore circumference and partially by the at least one step-like recess, wherein the respective step-like recess and the respective tab are radially outside the bore circumference.
  • the circular bore circumference can then, for example, have an internal thread that can be brought into engagement with an external thread of a screw.
  • the at least one step-like recess and the at least one tab are located radially outside the circular bore circumference, so that the connection of the internal thread of the respective Festlegbohrung with the external thread of a screw over the entire length of the respective Festlegbohrung is possible.
  • connection body can be securely fixed to the exhaust gas cooler and sealing of the exhaust gas cooler can be significantly improved.
  • the surface seal can also be rotationally fixed to the longitudinal axis of the respective fixing hole and twisting of the surface seal on the sealing surface can be avoided.
  • the second form-fitting contour is formed by a radially outwardly directed formation, wherein the shape and the step-like recess form a positive fit.
  • the radial formation can thereby radially outward by a few millimeters and correspond in approximately a width of the step-like recess of the first positive locking contour. So that the first positive-locking contour and the second positive-locking contour form a positive connection and the surface seal is disposed adjacent to the connecting body is a height of the step-like recess along the respective longitudinal axis and a distance of the formation on the tab to the respective fixing opening adapted to each other.
  • the second contour contour is formed by a radially outwardly directed edge, the edge and the step-like recess forming a form fit.
  • the edge may extend radially outward by a few millimeters and correspond approximately to a width of the step-like recess.
  • a height of the step-like recess along the respective longitudinal axis and a distance of the edge on the tab to the respective Festlegö réelle be adapted to each other, so that the edge and the step-like recess form a positive fit and the surface seal is arranged adjacent to the sealing surface of the connector body.
  • the second positive locking contour is formed by a radially outwardly directed and engaging behind edge, wherein the engaging behind edge and the step-like recess form a positive connection.
  • the trailing edge may facilitate locating the respective tab in the respective locating bore.
  • a height of the step-like recess along the respective longitudinal axis and a spacing of the engaging edge on the tab to the respective fixing opening are adapted to each other.
  • a width of the engaging edge may correspond approximately to a width of the step-like recess and be a few millimeters.
  • the second positive locking contour by a radially outwardly directed tongue element on the respective La see is formed.
  • the tongue element of the second positive locking contour and the step-like recess of the first positive locking contour suitably form a positive locking, so that the surface seal rests against the plate-shaped connecting body.
  • the radially outwardly directed tongue element can be punched out in the respective tab, for example.
