Vehicle IC engine dismantlable exhaust pipe - has flange connection with joint seals compressed via spring washers giving limited rotational flexibility

摘要

The flange connection for vehicle IC engine dismantleable exhaust pipes is partic. for bend-lengths ahead of the silencer, with a horizontal right angle followed by a vertical one. The joints embody sealing devices and are bolt-tightened. The bolting loads at either or both ends are applied to at least one of the flanges via spring washers (31). The bend's inlet end is supported rotationally flexibly from the engine-mounted pipe (1) via lugs (33,34) projecting sideways from the flanges (26,27), parallel to a common centre plane and overlapping to permit linking via one or more adjustable flexible elements (36,37).
