Abstract: An ink jet nozzle comprises a unitary construction of a nozzle plate having a jewel orifice on one face with a passage through the plate at right angles thereto for supplying ink to the nozzle under pressure, a reaction mass and a piezoelectric ceramic connecting the nozzle plate and the reaction mass. The assembly is secured to a support by a silicone rubber isolation damper which permits the nozzle plate, piezoelectric ceramic, and the reaction mass to vibrate as a unit at a selected frequency to effect uniform break off of ink drops from the ink stream issuing from the nozzle.
