FLEXIBLE COUPLING DEVICE FOR EXHAUST SYSTEMS

摘要

FLEXIBLE COUPLING DEVICE FOR EXHAUST SYSTEMS A flexible coupling device (140) for sealably connecting together first and second tubular bodies (30,70) which are subjected to pulsing pressures and to thermal expansion and contraction. The first tubular body (30) includes a first tubular portion (36) having a cylindrical end (44) and a flange (50) and the second tubular body (70) includes second tubular portion (76) having a planar mounting surface (82). The flexible coupling device (140) includes a guide ring (142) disposed in telescopic relation with the cylindrical end (44) of the first tubular body (30), a flexible bellows (160) having first and second attachment ends (166,168), a first retaining ring (174) for releasably securing the first attachment end (156) of the flexible bellows (160) to the flange (50) and a second retaining ring (174) for releasably securing the second attachment end (168) and the guide ring (142) to the planar mounting surface (82) of the second tubular portion (76).
