Docket 6303 APPARATUS FOR PRODUCING MULTIPLE UNIFORM FLUID FILAMENTS AND DROPS Abstract of the Disclosure Method and apparatus for use in an ink jet printing device to synchronously produce a plurality of uniform fluid filaments and droplets. A fluid reservoir is provided with an orifice plate having a plurality of orifices through which the fluid issues to produce the desired droplets. Above the liquid contained in the reservoir is a rigid piston suspended above the reservoir in contact with the liquid and having means sealingly engaging between the piston and the sides of the reservoir. The piston is moved translationally up and down by a plurality of electro-acoustical transducers which are secured to the piston in contact with its upper surface so as to produce pressure fluctuations in the fluid uniformly and synchronously over the plurality of orifices. -1-
