Abstract: A tube includes at least one fluoropolymer layer, the tube having an inner surface and an outer surface, wherein the at least one fluoropolymer layer includes a fluoropolymer having a heat shrink temperature of less than 250° C., wherein the outer surface of the tube is crosslinked and the inner surface of the tube is not crosslinked.

Abstract: An exhaust flap housing in which an exhaust flap can be disposed comprises at least one stop element for defining end positions of the pivotable exhaust flap. To simplify the production, the stop element is preferably produced by remodeling and thus forms part of the exhaust flap housing.

Abstract: An exhaust gas throttle means for motor vehicles comprises a housing in which an exhaust gas throttle is arranged. The exhaust gas throttle is connected with a throttle shaft which is supported in bearing elements. Inside the housing two stopper elements are provided which are arranged in recesses of the housing to be received in correct positional arrangement.

Abstract: An exhaust flap means for motor vehicles comprises an exhaust flap (10) connected with a flap shaft (12). In order to pivot the exhaust flap (10), the flap shaft (12) is connected with a pivot mechanism. The flap shaft (12) is supported via at least one bearing means (20) which comprises a plain bearing sleeve (22). The flap shaft (12) is radially supported by the plain bearing sleeve (22). According to the invention, a contact element (28) is connected with the flap shaft (12) to form an axial bearing. The contact element (28) bears on a face (26) of the plain bearing sleeve (22) and thus forms an axial bearing.

Abstract: An exhaust flap means for motor vehicles comprises a housing (10) in which an exhaust flap (12) is arranged. The exhaust flap (12) is connected with a flap shaft (14) for pivoting the exhaust flap (12). The housing (10) comprises two passage openings (22) opposite each other for guiding through the flap shaft (14). Further, two bearing means (18,40) for supporting the flap shaft (14) are provided. To permit an evening out of an offset between the two passage openings (22), one bearing means (18) comprises a bearing body (24) of ceramics, which has a spherical configuration. The opposite bearing means (40) comprises a bearing sleeve of graphite.
