Abstract
Embodiments of the invention provide a vibration damping system including a fixed element, a moveable element arranged to move linearly along an axis relative to the fixed element in response to a non-mechanical force, and an inerter element coupling the moveable element to the fixed element, and configured to convert the linear motion of the moveable element into rotational motion about the axis. The vibration damping system may be applied to many types of valves. In some embodiments, the vibration damping system may be applied to pressure relief valves. In some embodiments, the moveable element rotates to provide inertial damping. In other embodiments, the inerter element rotates to provide inertial damping.
