Abstract
A clamp device that is used to maintain a consistent clamping pressure on a flanged connection despite changes in temperature and changes in internal pressure behind the flanged connection. The clamp device contains a rocking bolt assembly that is manually tightened with a wing nut. Should the wing nut loosen, the rocking bolt assembly contains internal springs that compensate for the loosened wing nut and maintain a relatively consistent tension in the rocking bolt assembly within a predefined range of conditions.
