ABSTRACT:
An inkjet nozzle assembly comprises a nozzle chamber having a floor and a roof, the roof having a nozzle opening defined therein. A moving portion defines part of the roof so that the moving portion is moveable towards the floor. A thermal actuator defines part of the moving portion. The thermal actuator comprises a first active beam for connection to drive circuitry and a second passive beam mechanically cooperating with the first beam, such that when a current is passed through the first beam, the first beam expands relative to the second beam resulting in bending of the actuator. The first active beam is disposed on an upper surface of the passive beam relative to the floor.
