Definitions

  • the invention relates to a flat gasket, comprising at least one metallic layer which is provided with a plurality of fürgangsöffhungen spaced by webs, wherein at least in the region of one of the layers passage opening side at least partially a profile is arranged.
  • DE-A 3943177 is a metal plate with reinforcing bead and cylinder head gasket, which has the same, refer to.
  • the metal plate is provided with at least one partition portion between two adjacent cylinder holes, and at least one reinforcing bead is disposed in the partition portion so as to extend along the longitudinal direction thereof.
  • the reinforcing bead functions to reinforce, stiffen, solidify or the like the division region and to seal on and in the same.
  • the metal plate may also be assembled with other plates to form a steel laminate gasket.
  • the measures outlined provide for a relatively complicated construction in the bridge area, which is accompanied by considerable costs. '
  • WO 01/96768 a flat gasket and a method for its production is described.
  • the flat gasket is provided with at least one passage opening, wherein the or at least one of the metallic layers is formed at least partially in the form of a wave and / or sawtooth profiling around the passage opening (s).
  • the profiling is substantially similar, seen over the circumference of the through hole, formed, so that in the assembly of the gasket areas can be formed which do not allow optimum pressure.
  • the invention has the object of developing a generic gasket to the effect that in particular in critical areas of the gasket, the pressure can be variably influenced. This object is achieved in that the profile surrounding the respective passage opening with approximately constant cross-section and in the region of the respective web over a predetermined circumferential angle a different profile for increasing the pressure in this area is provided.
  • the gasket is formed by a cylinder head gasket for a Brenrikraftmaschine.
  • a modified profile is formed, which can be changed over a vorgebaren circumferential angle (10 - 120 °) targeted the pressure in this area.
  • the shape of the previously circulating waves is changed to a step-like profile.
  • the pressure in the desired manner can be variably influenced so that, when used as a cylinder head gasket, a wide variety of engine designs can be accommodated.
  • Figure 1 is a plan view of a portion of a serving as a cylinder head gasket gasket
  • FIG. 2 shows a section according to line A - A of FIG. 1
  • FIG. 3 shows a section along line B - B of FIG. 1
  • FIG. 1 shows a flat gasket 1 which can be used as a cylinder head gasket and which has a plurality of passage openings 2, which are spaced apart from one another by webs 3.
  • the peripherally formed profile 4 is transferred in the region of the web 3 into a step-like profile 5, the profiles 4, 5 seamlessly overflowing each other.
  • the stepped profile 5 is provided in this example over a circumferential angle ⁇ of 100 °. Different angles ⁇ can be provided depending on the embodiment of the flat gasket 1.
  • Figure 2 shows a cross section along line A-A of Figure 1. Shown is a part of the central web 3. Visible is a single step-shaped profile 5, which is approximately U-shaped in cross section and has a vorgebare width a. This step-like profile 5 is, seen in the direction of the adjacent passage opening, in a waveband 6 over. Viewed in the direction of the parallel passage opening 2, a similar profile can follow as required in mirror image form. Of course, alternative designs are also conceivable here, in that only one further step profile 5 is formed. "
  • Figure 3 shows a cross section along line B-B of Figure 1.
  • the section is provided outside of the web 3.
  • Recognizable is an over the remaining peripheral area (260 °) circumferentially formed wave profile 4 with vorgebarer width b and also vorgebarer number of wave crests 7 and troughs 8.
  • the width a, b and the height of the profiles 4, 5 and width and height of the wave area. 6 If necessary, they can be designed differently, so as to be able to bring about optimum compression of the cylinder head gasket 1.

Abstract

La présente invention concerne un joint plat (1) comprenant au moins une couche métallique qui présente plusieurs ouvertures de passage (2) écartées par des barrettes (3). Au moins une partie profilée (4) se trouve au moins partiellement au moins dans la zone d'une des couches côté ouverture de passage. Cette invention est caractérisée en ce que la partie profilée entoure chaque ouverture de passage avec une section transversale quasiment constante et en ce qu'une partie profilée d'un autre type (5) est placée dans la zone de chaque barrette (3), sur un angle de circonférence prédéfini (a), afin d'augmenter la pression dans cette zone.
