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.
Claims13
A valve comprising:
- a housing defining an inlet, an outlet, and a valve seat between the inlet and the outlet;
- a valve member coupled to the housing such that rotary movement of the valve member is inhibited, the valve member arranged at least partially within the housing and movable between an open position where flow is provided from the inlet through the valve seat to the outlet, and a closed position where flow is inhibited through the valve seat;
- and
- an inerter element arranged to convert linear motion of the valve member into rotary movement, thereby damping the valve.

- a valve member arranged at least partially within the housing and movable between an open position where flow is provided from the inlet through the valve seat to the outlet, and a closed position where flow is inhibited through the valve seat, the valve member coupled to the housing for linear movement relative to the housing along an axis and constrained such that the valve member does not rotate about the axis;
- and
- an inerter element coupled to the valve member and defining a cam profile, the inerter element arranged to rotate along the cam profile relative to the valve member about the axis in response to linear movement of the valve member.
