ABSTRACT:
In a flexible bellows used to implement some change of volume, material is added inside of the convolution walls to reduce the clearance volume associated with the fully compressed mode. For gas compression applications, this combination of bellows walls and independently-added filling material not only improves the volume and compression ratios available but also provides an opportunity to design for lower stress and longer life.
