Abstract
A micro-valve includes an orifice plate including a first surface and a second surface, and an orifice extending from the first surface to the second surface. The micro-valve also includes a spacing member disposed on the first surface and offset from the orifice, a valve seat disposed on the first surface. The valve seat defines an opening in fluid communication with the orifice in a flow direction. The micro-valve also includes an actuating beam disposed on the spacing member extending from the spacing member toward the orifice, the actuating beam being moveable between an open position and a closed position. The micro-valve also includes a sealing member affixed to an end portion of the actuating beam. In a closed position, a sealing surface of the sealing member contacts the valve seat to close the micro-valve.
