Abstract
A dual operating mode seal assembly (10) wherein a frictional force maintains a seal ring (50) in a static sealing mode during either movements of a member (16) being sealed to eliminate frictional and abrasive wear to the seal ring (50) and member (16). A load ring (52) provides a shear force upon deflection sufficient to overcome the frictional force at a predetermined slip point to cause the seal ring (50) to enter a dynamic sealing mode in response to extended travel movements of the member (16).
