| titleOfInvention | External manifold for ink jet array |
| abstract | ABSTRACT An impulse ink jet print head of the type including a plurality of operating plates held together in a contiguous superposed relationship. A plurality of piezoceramic transducers are mounted on a diaphragm such that each transducers overlies one of a similar plurality of ink chambers. The transducers are electrically energized and thereby caused to displace ink in the chambers resulting in the ejection of ink droplets through a plurality of nozzles, one nozzle being in fluidic communication with each of said chambers. An IC driver may be interfaced between an external control computer and the transducers to simplify the external circuitry necessary for operation of the print head. Ink is delivered to the chambers through compliant manifolds mounted externally of the print head, then through restrictor orifices formed in the same plate in which the nozzles are located. The construction allows for venting of the manifolds. The manifolds are constructed of material having sufficient compliance to absorb pressure waves which occur therein so as to avoid the undesirable phenomenon known as "cross talk" whereby pressure impulses intended for one system comprising an interconnected restrictor orifice, compression chamber, and nozzle are communicated to another such system in the print head. |
