Abstract
A flexible fluid conductive coupling for use with fluid flow systems has short fluid conductive cylindrical sections having different diameters so chosen that the smaller diameter section may fit within, and well clear of, the larger. A pair of external mating flanges are provided at the end and near the end, respectively, of the larger and the smaller cylindrical section, and a combination coupling and seal laminated from alternating layers of resilient and rigid materials is held in compression between these two flanges. The facing surfaces of the flanges are shaped to provide for the desired motion or displacement. The slight extension of the smaller cylindrical section into the larger provides a stagnation region between the two cylindrical sections, thereby protecting the seal from abrasive injury which might be caused by particulate matter in the fluid stream.
