    Abstract: 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.

  • Patent number: 8453680
    Abstract: 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.

  • Patent number: 7748749
    Abstract: For connection of pipelines which are subject to vibration, for example pipelines in vehicle exhaust systems, a liquid-tight decoupling element is used which includes a, e.g. multi-layer wound, metal hose and a tube accommodated in coaxial relationship inside or outside of the metal hose. A first axial fitting firmly secures one end of the tube. The tube is sized to protrude into a second axial fitting, regardless whether the metal hose is completely compressed or completely stretched, to allow movement of the tube in axial and torsional directions in relation to the second axial fitting.

  • Patent number: 7571745
    Abstract: For connection of exhaust system pipe work, which is subject to vibration, a typical example of an application being in vehicle exhaust systems, a gas-tight decoupling element produced from stripwound hoses is used, which consists of two coaxially arranged, multi-layer stripwound metal hoses and axial edge elements. These elements form an annular cavity between the two stripwound hoses with a suitable pneumatic connection which is pressurized in the operating condition using ambient air or cleaned exhaust gas, the pressure being as high or higher than the dynamic pressure which is built up in the inside cylindrical exhaust system cavity as a result of exhaust gas flow.
