Abstract
An apparatus for selectively controlling a flow of fluid includes a valve body, preferable comprised of a flexible tube having an inlet and an outlet. An actuable element, such as a shape memory alloy, is associated with the valve body. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape. When its shape changes, it causes a corresponding change in shape of the valve body thereby change a flow of fluid through the valve body.
