Abstract
A loading mechanism for a fluid seal that allows an installer to change or adjust the axial bias applied to a stacked set of sealing elements. The loading mechanism includes a bolt-like adjusting element that has a foot portion attached to one end and a rail element that is threadingly coupled at an opposite end. By rotating the adjusting element, the rail element can travel axially along the adjusting element. The axial displacement of the rail element allows the installer to select the amount of axial force or bias applied by the loading mechanism to the sealing elements.
