Variable valve with an electromagnetically-elongated actuator |
摘要 |
A variable valve with an actuator that elongates upon application of an electrically-derived field. The valve includes an actuator comprising an actuator member made of a material that is elongated by an electrically-derived field. A coil surrounding the actuator member selectively applies an electrically-derived field to the actuator member. The valve further comprises a fluid flow path, an opening in the fluid flow path defining a flow area, and a closure member movable by the actuator member from a closed or more closed position in which it is restricting some or all of the flow area, to an open or more open position in which it is restricting less of the flow area, to selectively alter the fluid flow rate through the opening.
