20090065976 | COMPONENT PART WITH INTEGRATED SEAL - A lid component part of an internal combustion engine with integrated elastic seal, such as, for example, is provided to a cylinder head gasket or oil pan and a process for its manufacture. The component part exhibits a circumferential flange area for the arranging of the integrated seal. The component part is based on a plastic-material, while the seal essentially comprises an organic elastomer material. The component part and the seal are chemically bonded with one another. The seal is applied by injection molding onto the component part. | 03-12-2009 |
20090217900 | Housing Part Having Sealing Face and Seal for Internal Combustion Engine - A housing part has a sealing surface around the housing part which is to be fastened by means of a seal to another housing part in a sealing manner. At least one fastening opening is provided for the guiding through of fastening elements, in order to seal the housing part on another housing part. At the at least one fastening opening, a ring-shaped projection is arranged which projects over the sealing surface and defines a minimum distance between the sealing surface of the housing part and sealing surface on the other housing part. | 09-03-2009 |
20090302551 | FLAT SEAL WITH ADHESIVELY BONDED OR INSERTED FUNCTIONAL ELEMENT FOR INTERNAL COMBUSTION ENGINE - A flat seal of a metal support with elastomer coating has areas which are usually stressed particularly intensively by local excess pressures and relative movements. Function elements are provided in these areas which relieve the stress of the seal. The function elements can be foils of metal or plastic which are glued on one side or on both sides. Alternatively, a flat metal or plastic element can be inserted into a free-stamped recess of the metal support of the seal and clamped in or glued on there. In both cases, by hardness, structuring and/or thickness of the function element, it is brought about that the forces occurring on the seal do not exceed the permissible material limits. Thereby, an excessive wear of the flat seal is prevented in applications having a high stress. | 12-10-2009 |
20100019459 | FLAT SEAL FOR HIGH LOADING FOR INTERNAL COMBUSTION ENGINES - A flat seal with increased wear resistance with respect to relative movements and local excess pressure includes a base support plate provided with profiling on both sides in the region of the fastening of the seal, which profilings lead to the surface being enlarge in this region and hence the forces being reduced, and also cause an increase in the friction or even a toothing effect with the pressed-on flanges. The profilings can lie freely or can be additionally coated or filled with an elastomer material. Through the local separation of functions which is thus achieved between sealing effect and fastening effect, a flat seal is provided which shows less wear and is therefore able to function for longer, without additional elements or costly processing steps being necessary. | 01-28-2010 |
20100166965 | SEAL WITH SUPPORT AND PRODUCTION OF SAME - The seal comprises a two-dimensional support, to which on one-side or both-sides an elastomer is applied by means of an injection molding process. The elastomer of the seal consists of at least one elastomer material. For the manufacture, a support is provided which is continuously fed to a pick apparatus, which cyclically applies on one or both sides an organic elastomer material as seal to the support. Subsequently, the seal is punched free. | 07-01-2010 |
20120152201 | COVER MOUNTING UNIT - The invention relates to a cover assembly unit comprising a thin-walled cover pan with a sealing flange, at least two screw holes in the sealing flange, at least one fixing opening, a fastening screw captively arranged in each screw hole; and a carrier frame gasket with a carrier, a gasket, which bears against the sealing flange, a screw passage for each screw hole, a fixing element for each fixing opening, and a centring body for the fastening screw in each screw passage. | 06-21-2012 |
20130183083 | TOLERANCE-OPTIMIZED SEALED JOINT AND PRODUCTION METHOD - A supporting frame seal includes a supporting frame with at least one inner opening; at least one sealing element which surrounds the inner opening; and at least one elastomer pin which projects from a first side of the supporting frame. The supporting frame has an opening which is aligned with the at least one elastomer pin. | 07-18-2013 |
20150137459 | CARRIER FRAME SEAL WITH IMPROVED SEALING EFFECT - A carrier frame seal for use in engine and cylinder components of internal combustion engines having improved sealing effect in the region of the connecting webs between different regions of the carrier frame. | 05-21-2015 |
