摘要： A micro-valve includes an orifice plate having a first surface, a second surface and an orifice extending from the first surface to the second surface. An actuating beam is disposed in spaced relation to the orifice plate. The actuating beam includes a base portion and a cantilevered portion. The base portion is separated from the orifice plate by a predetermined distance. The cantilevered portion extends from the base portion such that an overlapping portion thereof overlaps the orifice. The actuating beam is movable between a closed position and an open position. The micro-valve also includes a sealing structure including a sealing member disposed at the overlapping portion of the cantilevered portion. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve.

摘要： A micro-valve includes an orifice plate including an orifice and a cantilevered beam coupled in spaced relation to the orifice plate and moveable between positions where the orifice is closed and opened by the cantilevered beam. The cantilevered beam includes one or more piezoelectric layers that facilitate bending of the cantilevered beam in response to the application of one or more electrical signals to the one or more piezoelectric layers. In response to respective application and termination of the one or more electrical signals to the one or more piezoelectric layers the cantilevered beam either: moves from a starting position spaced from the orifice plate toward the orifice plate and returns back to the starting position spaced from the orifice plate; or moves from a starting position adjacent the orifice plate away from the orifice plate and returns back to the starting position adjacent the orifice plate.

摘要： Disclosed herein is a fluid supply system that can provide fluid to a jetting assembly at a constant pressure or at pressures within a desired range of pressures. In an example, the fluid can be ink, and the jetting assembly can be a print head configured for dispensing the ink.

摘要： A non-contact deposition system comprises a jetting assembly including at least one micro-valve. The micro-valve includes an orifice plate defining an orifice therethrough. An actuating beam disposed in a spaced relationship to the orifice plate. The actuating beam including a base portion and a cantilevered portion extending from the base portion towards the orifice and is movable between a closed position and an open position. A sealing structure comprising a sealing member is disposed at the overlapping portion of the cantilevered portion. A fluid manifold is coupled to the micro-valve and defines a fluid reservoir containing a pressurized fluid. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve, and in the open position, the fluid is dispensed from the orifice towards a substrate and deposited thereon.
