ABSTRACT:
A drop ejection device for continuous ink jet printing includes a rectangular solid divided by parallel, elongated through-slots between its major surfaces, into a plurality of approximately identical dilatational regions. Each such region has a longitudinal mechanical resonance mode approximately the same as the desired drop ejection frequency. The body has an ink supply manifold adjacent a drop ejection face, which is normal to the longitudinal axis of the through-slots. An orifice plate having a linear orifice array, substantially longer than the through-slots, is attached to the ejection face. A plurality of elongated piezoelectric strips pairs are attached in opposing positions on major surfaces of each dilatational region. Upon actuation, said strips expand and contract to effect synchronous stimulation at the desired drop frequency.
