Abstract: A system and method including a non-metallic shell to prevent debris from contacting a component of an exhaust system is disclosed. The shell may be formed from silicone. The shell may also form part of an assembly including a metallic corrugated body, which may be positioned between two pipe sections of the exhaust system. The shell may be separate from an exhaust coupler and be secured separately to the two pipe sections connected to the exhaust coupler.

Abstract: An exhaust connection coupler and a method for manufacturing a braid cover incorporated therein are provided. The method of manufacturing comprises the steps of providing a tubular sleeve formed of braided wire filaments and forming at least one end of the sleeve into shape using a forming die such that the at least one end of the cover includes a circumferential neck portion having a diameter smaller than the diameter of a body portion of the cover. In the method, the sleeve may be pressed between male and female forming dies in order to create the cover's desired shape, which can include a shoulder extending radially outwardly from the cover's neck portion and meeting the cover's body portion at a corner.

Abstract: A flexible conduit for use in a pipe system such as a vehicular exhaust system to provide a torsional or non-torsional joint between two pipes. The conduit has an outer bellows and an inner liner between which a layer of noise/thermal insulation is sandwiched to attenuate noise, resist thermal transmission and dampen vibration.

Abstract: An exhaust connection coupler is provided having a flexible conduit portion, a cover made of a generally porous and flexible knitted metallic wire mesh material surrounding the conduit portion and a retainer for combining end parts of the conduit portion and cover. The cover may be constructed of a series of stockinette stitches formed in a continuous round-and-round manner in a seamless tubular configuration. The cover can be selected from a group of covers designed to be applied to the coupler, the particular cover being chosen for its weight or stiffness so as to selectively control the natural frequency of the coupler. Additionally, the loosely knitted configuration of the cover is designed to provide resistance limiting longitudinal growth of the coupler while enabling compression and angular flexibility. Further, the coupler may include one or more spacers for providing separation between the cover and the conduit portion.

Abstract: An internally insulated rigid exhaust system conduit and method for making the same are provided. The conduit includes an outer rigid tube, a generally flexible inner portion positioned within the outer tube and an insulation layer positioned therebetween. The conduit may include one or more bends or curves. Due to the flexibility of the inner portion and insulation, a gap defined between the inner portion and outer tube may be generally uniform in width even after the bending of the outer tube. During the manufacturing process, the inner portion is wrapped with a blanket or sleeve of insulation material to form a wrapped subassembly and then inserted into the outer tube. The insertion of the wrapped subassembly may occur either before or after a bending of the outer tube. The insulation may also be blown into the gap defined between the inner portion and outer tube.

Abstract: A connection assembly for pipes is provided. The assembly includes a pipe, a corrugated conduit, a circumferentially contractible seal positioned between portions of the conduit and the pipe, a clamp encircling the conduit, seal and pipe, and a plurality of discrete projections on the inside of the seal to limit the extent of overlap between the pipe and the conduit. The seal is circumferentially contractible to secure the conduit and the pipe together with the seal serving to effect a gas-tight seal while filling the annular gap between the conduit and pipe.

Abstract: A flexible bellows tube connecting pipes in a system such as a vehicle exhaust system. Various embodiments are disclosed, with each including two conduit sections having mating corrugations that overlap to provide a seal while allowing the two sections to rotate in response to torsion loading. Different configurations of the interfitting corrugations and related structure are disclosed in the different embodiments.

Abstract: A self-sealing flexible metal hose includes a band adapted for winding on conventional winding equipment. The band includes receiver and insert assemblies adapted for interlocking with adjacent windings or turns of the band. A sealing flange provides continuous contacts and is urged into sealing engagement with the band by exhaust gas pressure within the hose bore. Alternative embodiments include different configurations of the flanges and legs which form the contacts, and accommodate packing material for greater sealing performance.
