Abstract: A filter for a fluid-conducting pipe, in particular for a gas-conducting pipe of an internal combustion engine. The filter includes a self-supporting areal filter element and is fixable along a circumference 2 directly or indirectly in the pipe and, in so doing, covers a free cross section of the pipe. Here, the circumference 2 of the filter element 1 circumscribes a central filter plane 4. Furthermore, the filter element 1 or at least one layer thereof is comprised of a plastically deformable material and is provided with at least one undulation 5 or bead 13, which does not intersect the circumference 2, in such a way that the filter element 1 intersects the filter plane 4, or a plane 4a parallel thereto, at least four times within the circumference 2.

Abstract: The invention relates to a plug connection that comprises a housing (1) with a receiving opening (2), for the insertion of a connection pipe (3), and a connection part associated with the receiving opening (3) for retaining the connection pipe (3) in the housing (1). The connection portion contains a clamping element (10) with several clamping segments (12), mutually separated by slots (11), and a supporting element (15), which works in cooperation with the clamping element (10), wherein the supporting element (15) presents mutually separated retaining tongues (16) for engagement in the slots (11) of the clamping element (10), and wherein the clamping segments (12) of the clamping element (10) contain conical outer surfaces (13) for application against a conical inner surface (14) of the receiving opening (2).

Abstract: In order to obtain optimum absorption and compensation of relative movements in an exhaust gas system while at the same time avoiding a transmission of movement and the occurrence of a resonance phenomena, a conduit element is proposed having a bellows and a metallic braided or knit jacket. The bellows is fashioned as a highly flexible bellows with an all around absorption of movement. The jacket is applied to the bellows so that the jacket solely follows substantially the wave crests of the bellows.

Abstract: For the vibration-based decoupling of two pipe parts, such as the exhaust pipe of an internal combustion engine and the exhaust system, at least two compressed absorber cushions of braided, knitted, tangled or similar wire are arranged so as to absorb or damp movements of substantially the same order of magnitude in all degrees of freedom, that is, with respect to all possible movements. For this purpose, the at least two absorber cushions each have a polygonal configuration.
