摘要： A pipe unit for arrangement in a conduit for a gaseous medium, comprising a pipe-shaped body, a pipe-shaped flexible sealing element, which is fixedly attached at a first end outside the pipe-shaped body and which comprises a flange element at a second end. The flange element is detachably attachable to a flange element in a connecting pipe in the conduit, in order to, when the flange elements are fixed to each other and the pipe unit is accordingly connected with the connecting pipe, to allow movement between the pipe-shaped body and the connecting pipe via the sealing element's flexibility. A mutual fixation of said flange element forms the only touching connection of the pipe unit to said connecting pipe.

摘要： An exhaust connection coupler and a method for manufacturing a braid cover incorporated therein are provided. The coupler may include an inner flexible bellows member and an outer braid cover surrounding the bellows member. The braid cover may be formed into a predetermined shape prior to assembly with the coupler. The braid member can include a generally cylindrical body section and two end sections each forming necks having diameters that are smaller than the diameter of the body section. The body section of the braid cover is self-supporting and is positioned an appreciable distance from the bellows member in order to avoid any friction and to create a thermally insulating air gap therebetween. The braid cover may be constructed of braided wire filaments that are formed into shape with forming dies. The braid cover may be pressed between two forming dies in order to create its desired shape.

摘要： An exhaust connection coupler and a method for manufacturing the same are provided. The coupler may include a bellows member, an interlock member disposed within the bellows member and an outer braid cover surrounding the bellows member. The braid cover is designed such that it provides resistance limiting axial growth of the coupler, so that the interlock member is not extended to an excessive length, while enabling maximized compression and angular flexibility. The outer braid cover may be constructed of intertwined bundles of wire filaments disposed at a specified angle from a central axis of the coupler. As assembled, the interlock member is at a nearly fully extended length when the bellows member is at an uncompressed and unextended length in order to maximize the amount in which the coupler may be compressed and/or flexed during installation and use.

摘要： A direction changing flow duct, for example, a compressor inlet duct (34) for a turbocharger compressor cover, wherein the direction of flow is made to change abruptly in a short distance. The direction changing segment is designed to provide a balanced output, optimize air flow, minimize pressure drop, and maintain compressor efficiency. This can be accomplished by providing a bulge (81, 83, 84) extending radially inwards into a first duct segment, outward bulges perpendicular to the inward bulge, for promoting flow attachment along the walls of the duct.

摘要： An exhaust system for the discharge of exhaust gases from a vehicle engine includes a resonator. The resonator comprises a resonator body having at least one, and preferably more than one, elongated composite strip. Each composite strip has a center foil which is corrugated to provide alternate ridges and grooves and is sandwiched between two perforated foils to provide a multiplicity of parallel fluid passages between the corrugated foil and the perforated foils. The composite strips are tightly wound about a central axis parallel to the fluid passages. A housing encloses the resonator body and has an inlet at one end of the fluid passages and an outlet at an opposite end of the fluid passages. The exhaust gases flow through the passages causing a break up and tuning of the sound waves in the system.
