| 20120125192 | DIAPHRAGM BELLOWS PRODUCED FROM PROFILED METAL STRIP - A profiled metal strip for a diaphragm bellows is made from a strip material having at least one border which is subjected to reverse bending. Such a metal strip is wound to produce a diaphragm bellows, with abutting borders of neighboring turns being connected with one another by a material joint, such as a welding seam. | 05-24-2012 |
| 20110232796 | STRETCHABLE STRIPWOUND HOSE - A stripwound hose expandable from a compressed state to a stretched state includes at least two spiral-wound strips having at least three telescoping portions in a direction of a longitudinal axis. The telescoping portions are arranged in axially overlapping relation, when the stripwound hose assumes the compressed state; and extend in axial side-by-side relation, when the stripwound hose assumes the stretched state. The telescoping portions are hooked to one another when being axially stretched. | 09-29-2011 |
| 20110209790 | DAMPING ELEMENT FOR DECOUPLING ELEMENTS, IN PARTICULAR FOR MEMBRANE BELLOWS - A decoupling element for a conduit includes an interior hose made of metal and a corrugated exterior hose surrounding the interior hose, with a hollow-cylindrical gap formed between the corrugated exterior hose and the interior hose. At least one damping element is arranged in the gap, with the damping element(s) constructed of a woven fabric made of a high-temperature-resistant material and having an outside surface with at least one bulge, wherein the bulge positively engages with a corrugation of the exterior hose. The exterior hose may be a membrane bellows. The woven fabric may be a metallic material. The at least one damping element covers, along the rotation axis, preferably a proportional length of at least 20% of the hollow-cylindrical gap and has preferably a static stiffness in the radial direction of less than 100 N/mm. | 09-01-2011 |
| 20100206419 | STRETCHABLE METAL TUBE - A tube is made of profiled metal strip which includes an end leg extending in parallel relationship to a tube axis, an inner leg extending in parallel relationship to the tube axis at a first distance, and an outer leg extending in parallel relationship to the tube axis at a second distance which is greater than the first distance. The inner leg is connected with the outer leg by a transition A double-folded loop hook extends radially for connecting the end leg with one member from the group consisting of the inner leg and the outer leg, and an end hook extends radially and is connected to the other member of this group. | 08-19-2010 |
| 20100007138 | HOSE CONNECTOR WITH TORSIONAL DECOUPLING - A hose connector, in particular for exhaust pipes of motor vehicles includes a flexible line element, for example a metal bellows which is supported at one end face in the support member of an attachment carrier with torsional degree of freedom. A tension element is provided by which the line element can be maintained under pretension against the support member of the attachment carrier. | 01-14-2010 |
| 20080264509 | SPIRAL-WOUND DIAPHRAGM BELLOWS, AND METHOD OF MAKING SUCH A DIAPHRAGM BELLOWS - A diaphragm bellows includes a spiral-wound, pre-profiled metal strip having neighboring turns which are connected by a continuous welding seam in an area of an outer diameter or inner diameter of the metal strip. Neighboring flanks of the metal strip enter a region of the welding seam at an angle of less than 60°. | 10-30-2008 |
| 20080245435 | STRETCHABLE METAL TUBE - A tube is made of profiled metal strip which includes an end leg extending in parallel relationship to a tube axis, an inner leg extending in parallel relationship to the tube axis at a first distance, and an outer leg extending in parallel relationship to the tube axis at a second distance which is greater than the first distance. The inner leg is connected with the outer leg by a transition. A double-folded loop hook extends radially for connecting the end leg with one member from the group consisting of the inner leg and the outer leg, and an end hook extends radially and is connected to the other member of this group. | 10-09-2008 |
