Cylinder head gasket with a ring-shaped metallic sealing element extending around a through-opening of the gasket, wherein, for automatic adaptation to changes in the width of the sealing gap to be sealed by the cylinder head gasket, the sealing element is of such spherical shape in cross section at its sides facing the two main surfaces of the gasket as to result in convex surfaces of the sealing element that face the main surfaces of the gasket and each have a crest, and, in the unpressed state of the gasket, these crests, in cross section perpendicular to the longitudinal center axis of a metallic sealing strand forming the sealing element, are laterally offset from one another in the direction of a gasket plane defined by the gasket so that the spacing of planes running parallel to the gasket plane and tangentially to the convex surfaces of the sealing element varies when these convex surfaces tilt about the longitudinal center axis of the sealing strand.

Cylinder head gasket is provided having a single-layered or multilayered metallic gasket plate with sealing beads in at least one metal layer, which are elastically deformable in height and surround the combustion chamber through-openings, and deformation delimiting devices which delimit the flattening of the sealing beads. In order to achieve as good a sealing function as possible in the long term and as good a protection as possible of the sealing beads against inadmissibly high deformations during operation of the engine, the deformation delimiting devices, one of which is formed by a meandering bead stamped into a metal layer, and the other by a plurality of elevations stamped out of a metal layer, are provided radially inside and radially outside of the sealing beads.

The invention relates to a metallic cylinder head gasket for an internal combustion engine, having a cover plate which faces the cylinder head of the internal combustion engine in the installed state and is provided with one or more openings arranged next to one another, corresponding to the combustion chambers of the internal combustion engine. The cover plate has a bead around each opening with a space between the bead and the opening. This leaves a straight sheet metal portion in the edge region of the opening. Arranged adjacent to the bead around each opening radially inwards from the respective bead facing away from the cylinder head is a stopper for the bead, which at the same time forms an upward combustion chamber extension of the seal. In this case, the stopper decreases in its thickness radially outwards in such a way that the surface pressure in the region of the stopper is essentially homogeneous over the width of the stopper under operating conditions.

A metallic cylinder head gasket for an internal combustion engine, has a carrier plate which is arranged between cover plates. The carrier plate and cover plates are provided with passages which are commensurate with the combustion chambers of the internal combustion engine. The cover plates are provided, around each passage, with a resilient bead. Adjacent to each bead, and also extending around each passage, is a bead deformation limiter. The deformation limiters are shaped to prevent the occurrence of high edge pressures.

In order to provide a cell connector for the electrically conductive connection of a first cell terminal of a first electrochemical cell and a second cell terminal of a second electrochemical cell of an electrochemical device comprising a base body and a contact body, which is connected to the base body and is connected to one of the cell terminals in the assembled state of the cell connector, at which an electric potential is detectable in a particularly simple manner, it is proposed that the contact body comprises a voltage tap.
摘要:
Cylinder head gasket whose gasket plate comprises a single sheet metal layer, combustion chamber openings, and for each combustion chamber opening a ring-shaped combustion chamber sealing element, which is a sheet metal ring that is arranged on the sheet metal layer and is joined to the latter by welding; to avoid the risk of damage to a combustion chamber sealing element as a result of sliding movements occurring between a cylinder head sealing surface and the cylinder head gasket while the engine is in operation, all sheet metal rings are arranged on that side of the sheet metal layer which is to face an engine block.
