A flexible membrane separates and fluidically seals the first and second liquid chambers from each other. The flexible membrane, residing in a first position, includes a residual compressive stress that exceeds an onset buckling stress of the flexible membrane. A heater, associated with the second liquid chamber, is selectively actuated to create a pressure pulse in a liquid that causes the flexible membrane to move from the first position to a second position to eject liquid through a nozzle of the first liquid chamber. In one embodiment, a liquid supply provides liquid that flows continuously from the liquid supply through the liquid supply channel through the second liquid chamber through the liquid return channel and back to the liquid supply during a drop dispensing operation.

摘要： A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.
