ABSTRACT:
A bellows is comprised of a unitary body formed of relatively thin annular walls, open at one end and closed at the other. The walls are constructed and arranged as a spiral groove, whereby the bellows can be fabricated from plastic by injection molding in a relatively inexpensive fashion. The bellows can be formed of two layers joined to one another, a backup layer formed of metal or plastic and a protective layer formed of plastic such as PFA and PVDF.
