ABSTRACT:
A pulsed droplet ink jet printer has at least one channel communicating with a nozzle. The side wall of the channel is formed as a shear mode piezo-electric actuator comprising an unpoled crystalline material. Electrodes applied to the actuator enable an electric field to be applied such that the actuator moves in transversely of the field to change the liquid pressure in the channel and thereby eject a droplet through the nozzle. The actuator can be made in two parts so as to deform, in cross section, to a chevron formation.
