Abstract:
1. A micro-electromechanical liquid ejection device that comprises a substrate that defines a liquid inlet channel; drive circuitry positioned on the substrate; a nozzle chamber structure positioned on the substrate and defining a nozzle chamber in fluid communication with the liquid inlet channel and a liquid ejection port in fluid communication with the nozzle chamber; a liquid ejecting mechanism operatively arranged with respect to the nozzle chamber such that movement of the liquid ejecting mechanism results in the ejection of liquid from the liquid ejection port; and an actuator fast with the substrate and connected to the drive circuitry to be displaced relative to the substrate on receipt of an electrical signal from the drive circuitry, the actuator being connected to the liquid ejecting mechanism, to cause said movement of the liquid ejecting mechanism, the liquid ejecting mechanism having a liquid ejecting member that acts on liquid in the nozzle chamber, the actuator and the liquid ejecting mechanism being configured so that an extent of displacement of the actuator is amplified in movement of the liquid ejecting member.
