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： An exhaust-gas conduction component that is effective as a vibration decoupling element and can be installed in an exhaust-gas system for conducting the exhaust gases of a motor vehicle internal combustion engine. The exhaust-gas conduction component (1) has an outer pipe (2) with a corrugated metal tube section (3; 4) and an inner pipe (8) that is coaxial with the outer pipe (2) and separated from the latter by an annular gap. The outer pipe (2) also has a smooth central section (5), first and second corrugated metal tube sections (3; 4) and smooth first and second end sections (6; 7). The inner pipe (8) is permanently fixed to the outer pipe (2) by a continuous joint (9) extending around the central section (5) and the rectilinear exhaust-gas conduction component (1) is approximately axially symmetrical in relation to a central transverse axis (10). The exhaust-gas conduction component is especially suitable in utility vehicles for linking an emission control unit to an internal combustion engine.

摘要： A method and preprocessed tube for producing a tube with a bent progression or bend embodied as a transverse progression. For the bent position of the tube or for each fold of the transverse progression, two miter cuts are made into an essentially straight tube, creating two tube sections with miter cut surfaces extending along cutting planes and a cutting wedge. The miter cuts are placed such that the cutting planes intersect at a point located inside the tube wall, and at this point a bendable bar is left intact connecting the two tube sections. A folding of the miter cut surfaces of the two tube sections onto each other around the bar acting as a hinge allows both tube sections to be welded together around their miter cut surfaces. An additional centering aid formed by a protrusion and a recess can be provided in the opposite miter cut surfaces.

摘要： Plug connection between a corrugated hose and an unprofiled pipe. A plug connection is provided between a corrugated hose (1) and an unprofiled pipe (31), a holding element (3, 34, 50) that surrounds the unprofiled pipe (31) being connected at least indirectly with the hose end (4), and the end (31) of the unprofiled pipe being surrounded by a sealing ring (16, 17, 30) that is situated before the holding element (3, 34, 50). The sealing ring is connected at least indirectly with the hose (1) so as to form a seal. It is provided that the holding element (3, 34, 50) is situated in the hose end (4) and is held thereby, at least indirectly, by mutual positively locking engagement in the axial direction, and that on the other side of the seal (17, 18, 30) a guide sleeve (18, 25) having an inner diameter that corresponds to the outer diameter of the unprofiled pipe (31) is situated before the holding element (3, 34, 50). The sleeve is held radially by the hose (1) practically play-free, and at least indirectly, by mutual positively locking engagement in the axial direction.

摘要： To prevent snap-over of a flexible connecting tube conducting solar-heated liquid to a mirror which follows the travel of the sun through the sky and then changes to an inverted "night" position, as shown in FIG. 1 at (a), a flexible corrugated or pleated tube or hose (6) with a braid (9) to form a multi-layered structure (6,9) is surrounded by a stiffening jacket (10) in the form of a spiral metal tube with interlocking adjacent windings. The stiffening jacket has the characteristic to dampen movement of the tube and additionally the tendency to retain the tube in straight or at least single-bend position, so that unstable double bends (FIG. 1, B, C) are avoided. This substantially increases the lifetime of the tube. A lubricant (15) may be introduced between the corrugated tube (6) or the braid (9) and the stiffening jacket (10). Preferably, the braid is a wire mesh or braid (9) surrounding the corrugated tube (6). The end portions, adjacent attachments to ducts (2) on the mirror and a fixed attachment (4) can be reinforced.
