Abstract: A flat gasket with at least one extended carrier layer is described. Such flat gaskets are for instance used as transmission plates or also as cylinder head gaskets. They are also used in the area of the exhaust line of a combustion engine. The at least one extended carrier layer has a first surface and a second surface opposite to the first surface. The layer also has a passage opening for a fluid which penetrates the carrier layer. The circumferential edge of each of the two surfaces has one or several projections which encircle the passage opening at least in sections and protrude into the passage opening. A functional element is arranged in the passage opening, which is held by the one or several projections in the passage opening.

Abstract: The invention relates to a metallic flat gasket comprising a gasket layer (2) having at least one combustion chamber through-opening (3) which is surrounded by an elastically deformable sealing element (4) which is configured in the form of an undulatory profiling (40) in the gasket layer (2) in such a way that on each of the surfaces (21, 22) of the gasket layer (2) at least two wave crests (41) and two wave troughs (42) are present. The thickness (hyl) of the gasket layer (2) in the region of the sealing element (4), in the unloaded state, is greater than the original thickness (alpha) of the gasket layer. Apart from the undulatory profiling (40), no further sealing or support elements are present around the combustion chamber through-opening (3). The sealing element has, when subjected to linear compression of from 500 to 2,800 N/mm in a direction which is substantially perpendicular to the plane (E) of the gasket layer, a thickness which is greater by from 0.05 to 0.

Abstract: A gasket may have at least one metallic layer with at least one combustion gas through-opening and at least one fastener through-opening. The fastener through-opening may be at least partially circumferentially bounded by a deformation limiter having a plurality of troughs and crests. All of the troughs and crests are substantially aligned with one another.

Abstract: A gasket has sealing layer(s) with beads which are assigned to passage opening(s), and stopper layer(s) with a stopper which limits the resilience of the bead(s). The stopper is composed of a plurality of directly successive ridge-shaped elevations and groove-shaped depressions, both being trapezoidal in cross section and both being formed in on both sides of the stopper layer, with setting angles of the trapezium flanks. The trapezoidal elevations of the one side are situated opposite the trapezoidal depressions of the other side. A cross section (Q1) which is delimited by opposing trapezium flanks which are adjacent to one another is the same or greater than a cross section (Q2) which is delimited between the opposing depressions of the two sides.

Abstract: The invention relates to a metallic-flat gasket (1) comprising at least a first and a second gasket layer (2, 3) in which a bead (20) is provided in at least the first gasket layer (2), said bead (20) surrounding in a self-contained manner a through-opening (4) extending through the flat gasket (1). The first gasket layer (2) has a smaller surface area than the second gasket layer (3) and leaves free an edge region (6) adjoining the outer edge (5) of the flat gasket (1). A compensating portion (7) is provided in an edge region (6) of the second gasket layer (3), which compensating portion (7) protrudes at least in the direction of the first gasket layer (2) and has a height which is less than the thickness of the first gasket layer (2). The compensating portion (7) is arranged at least in certain portions along the outer edge (21) of the first gasket layer (2) and consists of a large number of alternating elevations (31) and depressions (32) which are formed in-the second gasket layer (3).

Abstract: A gasket is provided that is suitable for use in connection with a cylinder head. The gasket includes a first outer plate including a compensating portion, a second outer plate including a compensating portion, and a compensating plate positioned between said first and second outer plates. Preferably, at least one of said first and second outer plates includes a bead positioned outside of, and in close proximity to, said compensation portion of said plate. The compensating plate includes a compensating element and an edge portion. In a preferred embodiment, the area between the compensating portions of said first and second outer plates defines a compensating area and said compensating element is positioned within said compensating area. If desired, the gasket may also include a spacer plate.
