FLUID JET PRINT HEAD AND STIMULATOR THEREFOR Abstract of the Disclosure A fluid jet print head includes an orifice plate defining a plurality of orifices from which fluid emerges, and a stimulator means mounted in contact with the orifice plate for vibrating the orifice plate to produce a series of bending waves. The bending waves travel along the orifice plate and break up the fluid into drops of substantially uniform size and spacing. The stimulator means includes a stimulator member of a length equal to an integer half wavelength of acoustic waves of a frequency f passing therethrough. The stimulator member contacts the orifice plate at one end of the member. A pair of piezoelectric crystals are mounted on opposite sides of the stimulator member and, when driven by an appropriate A.C. drive signal, cause acoustic waves of a frequency f to pass along the member. The member is supported at a nodal plane. The member may enter the print head manifold and contact the orifice plate internally, with a seal arrangement being provided at a nodal plane along the member. Alternatively, a pin, mounted on the end of the stimulator member, such as a half wave member, may be used to transmit mechanical vibrations to the orifice plate.
