Definitions
- the invention relates to a flat gasket, comprising at least one layer, which is provided with at least one substantially circular passage opening surrounded by at least one bead, wherein at least one stop element made of wire made of a memory metal is arranged in the region of the passage opening.
- the overlay consists of a memory metal alloy, such as a nickel-titanium alloy, a copper-aluminum-zinc alloy, a copper-aluminum-nickel alloy, a chrome-nickel-steel alloy or a manganese-silicon -Steel alloy.
- a memory metal alloy such as a nickel-titanium alloy, a copper-aluminum-zinc alloy, a copper-aluminum-nickel alloy, a chrome-nickel-steel alloy or a manganese-silicon -Steel alloy.
- DE-C 198 08 362 shows a flat gasket, with at least one or more gasket layers and at least one through opening, which is surrounded by at least one bead, and a stopper, which is arranged in the region of the edge of the through opening and a complete flattening of the prevents at least one bead in the installed state of the bead, the stopper comprising a ring which is produced by severing a section from a starting material of greater length and shaping the section into a ring.
- the ring surrounds the through opening several times and can consist of a material with a memory effect.
- the starting material should be essentially wire or ribbon-shaped and be provided with an essentially rectangular, trapezoidal, round, oval, barrel, pillow, spiral, N or U-shaped cross section.
- the stopper elements previously used in the prior art were not suitable for using the positive effect of the memory metal in such a way that it was possible to influence different pressure conditions, in particular in the combustion chamber area of cylinder head seals. It is therefore the object of the subject of the invention to remedy this with simple and inexpensive means and to provide a flat gasket with which a positive influence on the different compression ratios given in the combustion chamber area is possible.
- the wire seen in its circumferential and / or longitudinal direction, at least partially has a profile of a predeterminable geometric shape.
- a particularly preferred geometric shape of the wire is the wave form, which, depending on the respective application, is either provided only at predeterminable regions of the through opening, in particular the combustion chamber through opening.
- the subject of the invention is preferably applicable in the area of a cylinder head gasket for an internal combustion engine.
- the alloys mentioned therein can also be used here.
- With the subject matter of the invention it is possible to have a positive influence on the different pressure conditions, in particular in the combustion chamber area of the cylinder head gasket, by appropriately designing the wire. When the internal combustion engine heats up, additional pressure is generated in the necessary areas by the memory metal.
- FIG. 1 schematic diagram through a flat gasket
- FIG. 2 cross section through the area of a single through opening
- FIG. 3 partial representation of the stopper element according to FIG. 2.
- FIG. 1 shows a schematic diagram of a flat gasket 1 designed as a cylinder head gasket, comprising a plurality of essentially circular through openings 2 designed as combustion chamber through openings, in the area of which a merely indicated bead 3 is provided.
- a stopper element 4 extends between the bead 3 and the through opening 2.
- Figure 2 shows a partial view of a cross section through the passage opening 2.
- the flat gasket 1 is multi-layered and includes a spacer layer 5 and an upper and a lower bead layer 6.
- the through hole 2 is surrounded by a flare 7, with between the spacer layer 5 and the flare 7 is a wire 8 made of a memory metal alloy. It is not shown here that the wire 8 extends between the upper 7 ′ and the lower stop surface 7 ′′ of the flanging plate 7 in a wave-like manner.
- Figure 3 shows the subject matter of the invention, namely the wire 8, which, seen over its circumferential length, is at least partially provided with a profile.
- the In this case, geometric shape is formed by a shaft 9 running in its axial direction, which, if necessary, can only be provided at particularly critical points of the through-opening, in particular the combustion chamber area, in order to influence the different pressure conditions in this area in this way can.
- the memory metal alloy can thus generate additional pressure in the particularly critical areas.
- the wire 8 should have a round cross-sectional shape 10.
