Abstract
Embodiments provide a valve including a housing defining an inlet, an outlet, and a valve seat between the inlet and the outlet. The valve further includes a valve member arranged at least partially within the housing and moveable 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 further includes an inerter element arranged to convert linear motion of the valve member into rotary movement beginning at the closed position, thereby damping the valve.
Claims20
A valve comprising:
- a housing defining an inlet, an outlet, and a valve seat between the inlet and the outlet;
- 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;
- and
- an inerter element arranged to convert linear motion of the valve member into rotary movement beginning at the closed position, thereby damping the valve.
A valve comprising:
- a housing defining an inlet, an outlet, and a valve seat between the inlet and the outlet;
- 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 and rotary movement relative to the housing about an axis;
- and
- an inerter element substantially fixed to the housing and defining a cam profile, a portion of the valve member engaging the cam profile such that in response to a non-mechanical force the valve member moves between the open position and the closed position and linear motion of the valve member is converted to rotary motion of the valve member, thereby damping the valve when the valve member first leaves the closed position.
A method for damping a valve, the valve including a housing defining an inlet, an outlet, and a valve seat between the inlet and the outlet, a valve member arranged at least partially within the housing and moveable 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, the method comprising:
- engaging a cam profile defined in the inerter element with the valve member;
- and
- damping the valve by continuously rotating the valve member along the cam profile as the valve member moves from the closed position to the open position in response to a non-mechanical force and as the valve member moves from the open position to the closed position in response to a non-mechanical force.
