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.

A vibration damping system comprising:
- a fixed element;
- a moveable element inhibited from rotating and 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 along a cam profile.
A vibration damping system comprising:
- a fixed element;
- a floating element coupled to the fixed element for linear motion along an axis and constrained such that rotation of the floating element is inhibited;
- and
- an inerter element coupled to the fixed element for rotary movement about the axis and constrained such that the inerter element does not move linearly relative to the floating element, the inerter element rotating in response to linear movement of the floating element to convert linear energy to rotary energy.
