Linear spring electromagnetic grill ink jet printing mechanism

This patent describes a shuttered ink jet nozzle having a shutter located between the ink reservoir and an ink chamber so as to allow or restrict the flow of ink between the ink chamber and ink reservoir to thereby cause the ejection of ink from the. chamber, the shutter being actuated on demand. The shutter can an electromagnetic coil mechanism attracting a magnetic plate. The coil is anchored to a wafer and the magnetic plate is connected to a shutter plate and adapted to open and close over a series of shutter holes allowing fluid communication between the ink reservoir and the ink chamber. The actuator can include linear springs so as to amplify the travel of a shutter plate covering shutter holes upon activation of the actuator. The ink reservoir includes ink under an oscillating ink pressure which is ejected from the nozzle chamber when the shutters are in an open position. An array of ink jet nozzles can be constructed and grouped into phase groups and each phase group is activated in turn so as to reduce pressure requirements in an ink jet reservoir. The shutters can be used to cause ink to be ejected from the nozzle chamber, followed by leaving the shutter open during a subsequent high pressure period to allow rapid refill, followed by closing the shutter at the end of a high pressure cycle so as to restrict back flow of ink from the nozzle chamber to the ink reservoir.
