<p>A gasket for sealing the gap between two approximately parallel sealing surfaces which are displaced axially relative to each other during the assembly, during which the gasket follows one of the sealing surfaces and is compressed between said surface and the other sealing surface. The gasket body which is made of a soft elastic material, for example rubber, consists of two main parts (1) and (2) which are connected through a narrower connection piece in such a manner that the one part (2) can pivot relative to the other part (1). For the purpose of avoiding such a relative rotation of the gasket parts that the assembly becomes unsuccessful, it is suggested that the axis of the connection piece (3) extends diagonally from the point of attack (A) on the one part, namely the sliding part (2), towards the supporting surface (7) on the other part, namely the attachment part (1). The sliding part (2) may have a concave surface (4), and the connection piece (3) can have a less stiffness than the sliding part (2). The attachment part (1) can be connected to a reinforcement (17). Further, the sliding part (4) can be covered by a closed sliding jacket (18), and both ends of the sliding jacket can be attached to the front edge of the sliding part. The invention also relates to a method of manufacturing a socket joint having a gasket mounted therein, which is manufactured by placing the gasket on a construction mandrel (16) on which the socket (14) is formed, the gasket being disposed in a prestressed state on the construction mandrel (16) for thereby expanding to a larger thickness upon removal of the mandrel.</p> |
