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: The invention refers to a charge air hose for motor vehicles, comprising: a hose-shaped base member and a textile reinforcement. In a conventional charge air hose the textile reinforcement is embedded into the base member or it is arranged between two layers of the base member. A continuing dynamic load of the conventional charge air hose leads to delamination of the composite. To solve the problems known from the prior art, the invention provides a charge air hose for motor vehicles, comprising: a hose-shaped base member, a textile reinforcement arranged on the surface of the base member, wherein the hose-shaped base member is a vulcanized, elastomer-containing hose.

To improve the holding device such that it achieves improved acoustic decoupling together with a considerably simplified structure, it is provided that the insert includes a flexible device configured to close the insertion slot in the closed state of the lid at least in sections.

Abstract: The invention relates to a connection device for connecting a line for the transport of media, comprising a flange with a medium passage for passing through a medium along a flow direction, preferably along an axis of symmetry, and comprising a clamping means, the flange comprising a contact section and the clamping means comprising a clamping section, and the flange and the clamping means being separably connectable, so that an end section of the line can be clamped between the contact section and the clamping section, wherein the contact section is inclined with respect to the flow direction at least in sections, and the clamping section is inclined with respect to the flow direction at least in sections in the assembled state.

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 invention relates to a conduit, preferably a flexible hose, which is, at least sectionwise, provided with an eversion in an end portion thereof, said conduit having been everted in a plastic state prior to a solidification by means of which said eversion is fixed; in addition, the invention relates to a method for producing such a conduit.

Abstract: The present invention relates to an arrangement with a tubular element, preferably a pipe or a hose, and a coupling device, which exhibits a tubular section, the internal diameter of which is larger than the external diameter of the tubular element and in which the tubular element is in some sections arranged in the tubular section. To improve this type of arrangement, provision is made according to the present invention in that a pre-fabricated, preferably annular adhesive element of essentially fusible adhesive is arranged between the tubular element and the tubular section.

Abstract: The present invention relates to a coupler comprising a housing including an accommodating means into which an end section of a preferably rigid conduit, which includes at least one securing collar radially projecting relative to the conduit and preferably extending in circumferential direction of the conduit, can be inserted in a direction of insertion, and comprising a retaining means with which the inserted conduit can be secured in a direction opposite to the direction of insertion. To improve such a coupler, it is suggested according to the invention that a securing means should be provided which comprises a fastening section with which the securing means can be fastened in the housing of the coupler, and a securing section, and the securing section in the inserted state of the conduit should be spaced apart from the securing collar in a direction opposite to the insertion direction and adapted to be brought into engagement with the securing collar by the conduit being pulled out.
