Abstract: A flexible conduit element with an end portion that is designed for attachment to a rigid conduit element. The flexible conduit includes a bellows member, an interlock member, an outer fixing member and a connection nozzle. An attachment portion of the connection nozzle extends beyond the outer fixing member and the interlock member and ends in a flared shape to form a gas-tight seal.

Abstract: 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.

Abstract: A flexible tube for an exhaust pipe of an automobile includes a bellows member having corrugations thereon; an interlocking member positioned in the bellows member with a predetermined gap from the bellows member and having a spiral groove formed thereon to absorb deformation; a braid member positioned to surround the outside portion of the bellows member and braided to be flexibly deformed with a large displacement with respect to a displacement and tension in a compression direction; cap members coupled for fixing the braid member on the outside of the both ends of the bellows member; and intermediate members formed in the shape of a ring and having one end fixed to the bellows member and the other end fixed to the interlocking member by overlapping the interlocking member inwards, wherein the bellows member has protrusion portions, a center part and both end parts.

Abstract: The present invention refers to a flexible conduit element for an exhaust system of a combustion engine vehicle, comprising a helically or annularly corrugated metal bellows member, an outer flexible member disposed around the bellows member and the resilient member biasing the flexible outer member towards the metal bellows member. In order to improve the absorption of vibrations of a combustion engine, the outer flexible member comprises a reticulated structure.

Abstract: A flexible tube for an exhaust pipe for an automobile includes a bellows member (10) corrugated to have alternate ridges (11) and furrows (12) along its outer periphery; outer braids (20) provided to enclose the bellows member (10); fixing caps (30) fitted onto both side ends of the outer braids (20) respectively; and a spring member (40) provided on a circumferential surface of the outer braids (20). The bellows member (10) has lower ridges (13) in its center as well as regular ridges (11) on both sides thereof to more effectively absorb over-vibration of an exhaust system of an automobile and to enhance durability of the bellows member (10).

Abstract: An exhaust pipe decoupler for vehicles including a bellows (10), an outer braid member (20) spaced from the bellows and braided with a predetermined angle, a retainer (30) having a support (31) inwardly curved at both ends thereof for engaging to a ring damper (40), the retainer being affixed to the ends of the bellows (10) and installed between the outer surface of the bellows (10) and the outer braid member (20) to prevent direct contact thereof, the ring damper (40) located outward the support (31) formed in the retainer (30), a fixing cap (50) coupled to the outer diameter of the outer braid member (20) in order that the outer braid member (20) and the retainer (30) are located outward the bellows (10), wherein the outer braid member (20) absorbs tension in excessive outer forces, i.e., displacement of tension and compression, and the ring damper (40) controls the displacement of compression and shear displacement by the ring damper (40), thereby controlling the bellows within the elastic range.

Abstract: This invention relates to a decoupler for the exhaust pipes of automobile.
