Abstract: In an uncoupling element for uncoupling vibrations of the turbocharger of an internal combustion engine from an exhaust system with a bellows, provisions are made, especially for achieving a lower stiffness with short overall length, for the bellows to be a diaphragm bellows.

Abstract: A heat-insulated wound hose is formed by a process, in which a metal wound hose is at first upset, such that turns, which are spaced apart by adjacent axial wall areas of individual turns, form at least one uninterrupted jacket wall surface. A ceramic-based coating is subsequently applied to the at least one uninterrupted jacket wall surface. The coating is then cured, and the wound hose thus formed is subsequently pulled apart, whereby adjacent axial wall areas of adjacent turns are detached from one another and thereby the coating is broken up at partitions.

Abstract: A heat-insulated wound hose is formed by a process, in which a metal wound hose manufactured in the conventional manner is at first upset, such that turns, which are spaced apart by adjacent axial wall areas of individual turns, form at least one uninterrupted jacket wall surface. A ceramic-based coating is subsequently applied to the at least one uninterrupted jacket wall surface. The coating is then cured, and the wound hose thus formed is subsequently pulled apart, whereby adjacent axial wall areas of adjacent turns are detached from one another and thereby the coating is broken up at partitions.

Abstract: Connecting ends on a hose piece comprising several metal layers, in particular a strip wound metal hose piece, are produced by fixing the overlapping metal layers of a hose of larger length or of an endless hose in the region of the point of separation through welding and subsequently cutting off the hose piece from the longer hose or the endless hose. For simple and inexpensive fixing of the metal layers in the region of the point of separation, a welding seam is generated which extends through at least part of the periphery of the hose or about its entire periphery, using roller seam welding. The hose piece can subsequently be separated along the welding seam obtained in this manner, e.g. along its central line, thereby ensuring permanent and reliable fixing of the metal layers in the region of the connecting end.

Abstract: Connecting ends on a tube piece comprising several metal layers, in particular a wound metal tube piece, are produced by fixing the overlapping metal layers of a tube of larger length or of an endless tube in the region of the point of separation through welding and subsequently cutting off the tube piece from the longer tube or the endless tube. For simple and inexpensive fixing of the metal layers in the region of the point of separation, the invention proposes effecting a welding seam which extends through at least part of the periphery of the tube or about its entire periphery, using seam welding. The tube piece can subsequently be separated along the welding seam obtained in this manner, e.g. along its central line, thereby ensuring permanent and reliable fixing of the metal layers in the region of the connecting end. The invention also concerns a tube piece having a connecting end produced in this manner.

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.
