Abstract:
An ink jet printing device includes a pressure chamber, a first actuator membrane being arranged to form a first flexible wall of the pressure chamber, a first piezo-electric part being operatively connected to a surface of the first actuator membrane, a second actuator membrane being arranged to form a second flexible wall of the pressure chamber and a second piezo-electric part being operatively connected to a surface of the second actuator membrane, wherein the second flexible wall is mechanically decoupled from the first flexible wall.
