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 when the moveable element begins to move linearly. 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 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 when the moveable element begins to move linearly.
A vibration damping system comprising:
- a fixed element defining a cam profile;
- and
- a floating element coupled to the fixed element and moveable relative to the fixed element between a first position and a second position,
- the cam profile converting linear motion of the floating element into rotational movement of the floating element to provide inertial damping as the floating element first leaves the first position and as the floating element first leaves the second position.
A method of damping vibrations comprising:
- linearly moving a floating element along an axis relative to a fixed element in response to a non-mechanical force;
- and
- converting the linear motion of the floating element into rotational motion of the floating element along a cam profile defined by the fixed element when the floating element first begins to move linearly.
