摘要： A line element for compensating for expansions and/or relative movements within a line through which fluid can flow, comprising a ring-corrugation or helical-corrugation bellows 1 and a hose 3, which is arranged coaxially in the interior of the bellows 1 and is made of a dimensionally stable material, for flow-guidance purposes. The hose 3 has a number of individual, essentially dimensionally stable ring-form hose elements 4 which are plugged axially one inside the other so as to be retained such that they can be moved axially and/or angularly in relation to one another between a compressed position and an extended position. A method for producing such a line element is also provided.

摘要： 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.

摘要： A method for cutting a wound hose (1), made form mutually engaging windings (11, 12, 13, 14) of a metallic tape (2), with the wound hose (1) being welded in a predetermined axial area (10) and then cut within the area (10) essentially in a plane (6) extending radially, with the wound hose (1) being axially compressed in the predetermined area prior to welding such that in the area (10) a mutual contacting of the windings (11, 12, 13, 14) occurs. The welding is performed along a predetermined number of windings (11-14) in the area (10), and the welding energy required for welding the windings is introduced via the area of the winding hose into it. Additionally, an accordingly produced wound hose (1) is provided and a device suitable for its production.

摘要： A connection for spirally corrugated piping sections of metal for material sold by length with a continuous cross section. The connection is produced without a separate sleeve in that the ends of two piping sections to be joined with each other are brought into a smooth cylindrical form, and one of the two ends is enlarged in relation to the other cylindrical end. The ends are fitted into each other, and mutual fixation takes place through a glue connection.
