Abstract
A rotary damper ( ) includes a stationary member ( ) and a rotating member ( ) provided within the stationary member ( ) so that a gap ( ) is defined between the rotating member ( ) and the stationary member ( ). The rotating member ( ) further includes a central shaft ( ) provided therein. A viscous fluid ( ) is provided in the gap ( ) and has an associated shear that provides a velocity damping within the gap ( ). A differential growth in the gap ( ) caused by temperature variation compensates for temperature damping variation. A compliant member ( ) is provided within the stationary member ( ) for providing thermal compensation. A secondary hermetic seal ( ) is provided on the stationary member ( ) for permitting limited rotation, defining a vacuum environment and preventing viscous fluid leakage to an external environment.
