ABSTRACT:
An impulse ink jet apparatus includes a plurality of lengthwise expandable piezoelectric transducers, each of the transducers varying the volume of a compression chamber in order to eject droplets of ink therefrom. Mechanical cross talk propagating along a support structure for the transducers is minimized by effectively decoupling each transducer from its neighbors. In one approach, the support structure rigidly supports each transducer at displacement nodal points thereof, while in another approach the lengths of the transducers are uniquely varied with respect to their neighbors.
