ABSTRACT:
In an embodiment thereof, the closure device comprises a leaf-type, planar, closure element pivotally coupled to a supporting shaft. The shaft is fixed in traverse of a fluid conduit, and the closure element is rotatable therewithin for opening and closing the conduit to fluid flow. Shape-memory alloy components are engaged with the element, and a bearing surface, to cause the element to move from an opened or closed position to the other thereof, or to some intermediate positioning for metered or damping fluid flow, in response to prescribed temperatures.
