Abstract
A pressurized fluid issuing from a nozzle orifice to form a jet stream is perturbated by a hybrid velocity and pressure modulation to form a stream of drops. A perturbation means, such as a piezoelectric crystal, is mounted both to vibrate the nozzle for modulating the stream velocity and to perturbate the interior volume of a fluid cavity communicating with the nozzle for also modulating the pressure of the fluid.
