Embodiment Construction

[0022] figure 1An embodiment of a gasket 10 according to the invention with an elastic bead 11 injection-molded on a support frame 12 is shown. The elastic sealing edge 11 has a defined outer contour which matches the contour of the corresponding molded part. In the inner area of ​​the gasket 10 , the middle connecting piece 13 is arranged on the support frame 12 , and the middle connecting piece can enhance the stability of the whole gasket 10 . The height of the sealing edge 11 starting from the gasket plane clearly exceeds the thickness of the support frame 12, thereby ensuring that, when the two molded parts are assembled with the inserted gasket, the sealing edge will be at any point on its contour. can be compressed. An indicator 14 is arranged on the outer circumference of the sealing lip 11 . This indicator 14 is to be injected onto the support frame 12 together with the sealing bead 11 in an injection mold. It is not meant to interrupt the sealing edge, so the sea...

Abstract

The invention relates to a seal (10), in particular a valve-cover seal or cylinder-head cover seal, for sealing a connection between a substantially thin-walled moulded part (19) and an additional moulded part (17). Said seal (10) comprises an elastic sealing lip, which is located between the two moulded parts (19, 17), said elastic sealing lip being moulded onto the external edge region of a dimensionally stable support frame (12).

Description

technical field [0001] The invention relates to a gasket for sealing the connection of two molded parts, in particular a valve cover gasket. Background technique [0002] Thin-walled molded parts, such as valve covers or cylinder heads of internal combustion engines, have elastic gaskets that are connected to another molded part for sealing. DE 19738275 discloses an elastic gasket to ensure the static sealing of thin-walled covers of internal combustion engines. The thin-walled cover here has a surrounding fastening flange with a surrounding groove, which is used to accommodate the elastic gasket. It is proposed here that the elastic gasket has a projection which is intended to engage around the outer edge of the fastening flange, wherein the hook edge can engage the fastening flange from behind. In this way, a form-fit locking of the gasket on the lid can be achieved. The disadvantage of this solution is that the construction of the sealing gasket with hooked edges and p...
