The blocking layer can include a thermoplastic fluoroelastomer and/or a thermoplastic fluoroelastomer vulcanisate. A tank filling device can include at least one filling nozzle in which the multi-layer conduit is provided.

Abstract: The present invention refers to a fuel line for conveying fuel from and/or into a fuel tank. To suggest a fuel line for conveying fuel from and/or into a fuel tank (tank line), which can be processed easily and shows good mechanical properties and also a high chemical resistance, it is provided according to the invention that the fuel line consists essentially of F-TPV.

Abstract: The present invention relates to a multilayer pipe or hose, in particular a plastic pipe, comprising at least one polyester barrier layer and at least one additional protective layer, the additional protective layer being a polyethylene layer, in particular a HDPE layer, and the barrier layer and the protective layer being are interconnected via at least one adhesion promoter layer.

Abstract: To provide an assembly, comprising an exhaust gas turbocharger and an intercooler for an internal combustion engine and a hot-side charge-air line connecting the exhaust gas turbocharger to a charge-air inlet of the intercooler, which assembly allows the movements to be equalised between the exhaust gas turbocharger and the intercooler and is simple to produce and assemble, it is proposed that the hot-side charge-air line comprises a one-piece plastics material tube which is formed from a material containing polytetrafluoroethylene and/or modified polytetrafluoroethylene and has at least one flexible zone.

Abstract: The present invention relates to a hollow body, in particular a tube or pipe, comprising an inner layer and an outer layer, each made from a thermoplastic material, and two barrier layers provided between the inner layer and the outer layer.

Abstract: The invention relates to a silencer comprising an inner component and an outer component surrounding said inner component, said inner component defining an inner wall provided with openings and said outer component defining an outer wall extending along said inner wall. For improving the silencing characteristics as well as the flexibility of the silencer, the outer wall is implemented as a bellows which defines together with the inner wall individual cavities, the openings of the inner wall opening into said cavities. Furthermore, the outer wall is produced from a material having a density of at least 1.5 g/cm3.

Abstract: A flexible hose is disclosed, e.g., a charge-air hose for the automobile industry. A charge-air hose has rigid and flexible sections, which can be manufactured at lower costs and is less prone to material failure during permanent use than is a conventional hose. An exemplary flexible hose comprises at least one crosslinkable material, wherein the hose has crosslinking degrees differing in portions.

Abstract: The invention relates to a flexible hose, preferably a charge air hose, with a wall having at least partly an elastomeric material, in which a pressure support is arranged, which has at least one essentially threadlike or wirelike pressure support element. In order to improve a flexible hose of this nature such that it exhibits a longer service life in comparison to known hoses, provision is made that the pressure support element is movable at least partly with respect to the wall.

Abstract: The invention relates to a flexible hose, in particular, a charge air hose, with at least three layers, whereby one layer is formed as a reinforcing layer and two layers comprise an elastomeric material, whereby one of the three layers contains acrylate rubber (ACM).

Abstract: The present invention relates to a stabilization means for a corrugated hose comprising at least one corrugated portion with at least one corrugation which projects relative to the corrugated hose and which extends, at least in certain sections thereof, essentially in the circumferential direction of said corrugated hose, said stabilization means comprising at least one annular segment which, when mounted on said corrugated hose, surrounds the circumference of said corrugated hose adjacent the corrugation. For improving the vibration behaviour of corrugated hoses, in particular of charge air hoses, the present invention is so conceived that a stabilization means is provided, in the case of which the annular segment is a substantially planar structure comprising individual threads or strands that are arranged relative to one another.

Abstract: The present invention relates to a multilayer flexible hose, preferably for fuel or coolant lines in an automotive vehicle, comprising a support layer and a metallic barrier layer which is fixedly connected to said support layer, and to a method of producing the same.

Abstract: In order to effect an impervious and, at the same time, stable connection of fluid-conducting ducts, especially of hoses or pipes, a coupling having a connector is provided in accordance with the invention, which cooperates with a duct at least portion-wise, with the connector comprising at least one adhesive space which is filled with an adhesive. According to the method of connecting ducts a coupling according to the invention is used, whereby the connector of the coupling is, for instance, mounted on a duct and a thermal treatment is carried out, during which both the adhesive is hardened and the duct is thermally deformed.

Abstract: The present invention relates to a line, in particular for fuel tank filler systems, which comprises a blocking layer 1 and a cover layer 3. For improving especially the mechanical properties, the blocking layer 1 and the cover layer 3 have provided between them an intermediate layer 2 which is made of nitrile butadiene rubber and which has admixed thereto an adhesion promoter made of a phosphonium compound.
