Problems solved by technology

However, the elastic properties of the bead decrease over time
Excessive seal gap vibration can also lead to overloading of the bead
This can lead to a reduction in bead strength and elastic potential energy, or, even to bead rupture

Embodiment Construction

[0029] figure 1 Details of the metal layer 1 within the flat gasket are shown. A profile 5 is embossed as a detent on the metal layer, which profile has a corrugated structure 5a on one side and a contour 5b consisting of a corrugated structure with flat bottoms on the other side. The height 10 of the profile extends between the amplitude of the undulating structure and the amplitude of the peaks of the profile. A bead 7 is arranged close to the brake, the bead 7 having a height 20 . The height 20 of the bead is greater than the height 10 of the profile. The bead does not necessarily have to be imprinted onto the metal layer in the same direction as the wave structure, it can also extend in the direction of the profile.

[0030] figure 2 A schematic side sectional view of a part of a flat gasket with another embodiment of the profile according to the invention is shown. The metal layer 1 of the flat gasket has a contour 5 . The profile 5 includes a corrugated structure ...

Abstract

A flat seal having at least one metallic layer (1) is disclosed, wherein the at least one metallic layer at least partially comprises a profile (5) having an undulated structure (5a) in the cross-section on the side of the metallic layer. The profile (5) on the side opposite of the undulated structure (5a) has a contour (5b, 5c, 5d) in which rounded sections and those provided with edges alternate.

Description

technical field [0001] The invention relates to a flat gasket with at least one metal layer, in particular a metal layer used as a gasket for deformation limitation. The metal gasket is particularly useful as a cylinder head seal for sealing components within an internal combustion engine, but can also be configured for other types of seals, such as flange seals. Background technique [0002] Cylinder head seals are sandwiched between the engine block and the cylinder head of an internal combustion engine system. Its main task is to seal the combustion chamber, oil pipes and coolant area. It also acts as a force transmission component between the cylinder head and cylinder block. Seal gap vibrations that occur when the engine is running must be elastically compensated. [0003] In order to ensure or increase the sealing effect of cylinder head seals, especially around through holes such as combustion chamber openings or areas around coolant and engine oil passages, at lea...
