A gasket is described herein. The gasket might be used between internal combustion engine components. The gasket might be comprised of metal. The gasket might have several layers including a sealing layer and a compression layer. The gasket includes sections having different radii of curvature. The different radii of curvature might have particular relationships to one another.

Flat gaskets and the use thereof

A flat gasket for an internal combustion engine is described. The gasket may be used in the hot gas region of the internal combustion engine.

Flat gasket and internal combustion engine

A metallic flat gasket having a through-opening which is covered by a sieve element is described. The gasket serves for sealing a line transition between two components and for capturing particles in the fluid flowing through the line. At leat one metallic layer of the flat gasket has at least two continuations, which extend from the edge of a through-opening into the region of the through-opening, the at least two continuations being curved such that at least two of the continuations merge into each other in one plane or are connected together.

Metallic flat gasket

Transmission control devices may have two control boxes, and a planar transmission control plate disposed between the two control boxes. The transmission control plate seals the intermediate space between the two control boxes or the channel portions and borings thereof in the form of a flat gasket. The plate also makes available throughflow-openings between channels or borings in the control boxes for a fluid, the fluid in the channels controlling the function of a transmission. The sealing function is achieved by embossed beads and/or partial coatings.

Transmission control device

A transmission control device has two mutually oppositely arranged counter-components, for example control boxes, and a planar transmission control plate, which is arranged between the two counter-components. The transmission control plate seals the clearance between the two counter-components or their channel portions and bores in the form of a flat seal. The plate also provides through-openings between channels or bores, respectively, in the opposing counter-components, where the fluid in the channels controls the function of a transmission. The sealing function is realized by stamped beads and/or partial coatings. Transmission control plates therefore have fluid through-flow openings so the fluid can flow through from one side of the plate to the other side of the plate. Additional functional elements can be present in the through-flow openings, for example valve elements which stop the through-flow in one direction or combined valve-orifice elements, which restrict the through-flow in one or both directions.

A metallic flat gasket with at least one metallic layer and at least one filter element. The at least one metallic layer has at least one passage opening, which is covered by the filter element. The filter element has a mesh material.

The invention relates to a sealing system consisting of a first part and a second part and at least a passage opening extending in both parts, in particular a passage opening for fluids such as hot combustion gases from combustion engines as well as a corresponding metallic flat gasket such that the sealing system comprises or consists of a first part and a second part with the first part and the second part being compressed against each other at a joint contact surface and comprising at least one passage opening in the contact surface, which protrudes into the first and/or second part, an annular groove, which is delimited by the first and the second part and which encircles the passage opening, with the first and second part in the area at least radially outside of the groove come to rest one on the other.

Sealing system

The present invention relates to a control plate as it is for instance used in pneumatic or hydraulic controls. An example of such a control plate is a transmission control plate with which automatic transmissions are controlled hydraulically.

Control plate

The present invention relates to a flat gasket with filter elements. In order to fulfill the increased requirements with respect to cleanliness, there is an increased demand for the integration of filter elements in flat gaskets. The corresponding filter elements mainly serve for picking of impurities accrued during production as well as other residues circulate via the operational fluids, especially during the initial period of operation of an internal combustion engine or a vehicle.
