The present invention refers to a flexible conduit element for the joint between an exhaust gas system and a combustion engine of a vehicle, comprising a bellows member (2) which defines a guiding channel for guiding the exhaust gas of the combustion engine to an exhaust gas system, wherein at least a portion of a side surface of the bellows member comprises a coating (80) with nano-particles including materials for improving the corrosions resistance of the bellows member, and to an exhaust gas system including such a flexible conduit element.

The current invention comprises a flexible conduit means for an exhaust system of a combustion engine vehicle, comprising a bellows member (2), an outer flexible braided or knitted member (3) enclosing the bellows member, a resilient member (4), that is elastically deformable and encloses the outer braided or knitted member at least partially and abuts against it, whereas the bellows member comprises two corrugated portions (21), a connecting portion (24) between the corrugated portions, and the resilient member (4) encloses the connecting portion at least partially, the connecting portion (24) comprises flanks (25) that are formed at its axial ends and extend at least in a radial direction, and a curved portion (26) which connects the flanks with each other and which is at least partially enclosed by the resilient member (4).

The present invention relates to a device for transferring exhaust gas between a front and rear carriage of a mobile working machine, in particular a dump truck, separated by an articulated pivot joint, which working machine has a pipe section, which is variable in it length, for conducting exhaust gas, a first flexible hose cooperating with a first end portion of the pipe section for introducing exhaust gas into the pipe section, and a second flexible hose cooperating with a second end portion of the pipe section for discharging exhaust gas from the pipe section. The device is characterized in that a first cardan shaft is provided in the first end portion, the distal end of which is configured to be rigidly attached to a fastening section of the front carriage or the rear carriage of the working machine, and a second cardan shaft is provided in the second end region.

The damper segment can be assembled between adjacent segments of a pressurized gas pipe of an aircraft engine. The damper segment can have a proximal end, a distal end, a rigid tube at the proximal end, a damper tube extending between the rigid tube and the distal end, the damper tube being made of a metal mesh, a proximal catch structurally connecting a proximal end of the damper tube to the rigid tube, and a distal catch structurally connected between a distal end of the damper tube and the distal end, the damper tube having an unsupported length extending between the distal catch and the proximal catch, the rigid tube having a liner portion projecting into the distal segment, the liner portion extending internally relative the damper tube.

The current invention comprises a flexible conduit means for an exhaust system of a combustion engine vehicle, comprising a bellows member (2), an outer flexible braided or knitted member (3) enclosing the bellows member, a resilient member (4), that is elastically deformable and encloses the outer braided or knitted member at least partially and abuts against it, whereas the bellows member comprises two corrugated portions (21), a connecting portion (24) between the corrugated portions, and the resilient member (4) encloses the connecting portion at least partially, the connecting portion (24) comprises flanks (25) that are formed at its axial ends and extend at least in a radial direction, and a curved portion (26) which connects the flanks with each other and which is at least partially enclosed by the resilient member (4).

Proposed is a line assembly (1), including: a metal hose (2) that is corrugated at least in some segments; and an inner component (3), which is arranged radially inside the metal hose at least over a partial length of the metal hose; the line assembly being distinguished by at least one coupling element (4, 4), which coupling element is arranged between an outer border (2d) of the metal hose (2) and an outside surface (3a) of the inner component (3) and which coupling element is designed to damp the metal hose (2) by means of mechanical coupling to the inner component (3).

A flexible tube for an exhaust pipe of an automobile is disclosed, of which the bellows member has protrusion portions, a center portion and both end portions such that the protrusion portions have a uniform outer diameter, and the center portion has a maximum depression inner diameter which is larger than a minimum depression inner diameter of the both end portions, and the outer cover member is formed of an outer net with a network structure, wherein a depression inner diameter in the center of a bellows is larger than a depression inner diameter at the both ends such that a gap from an interlocking member increases so as to prevent the interference between the bellows and the interlocking member.
