  • Droplet generator
    Patent number: 8662646
    Abstract: The present invention provides a droplet generator (10) of the velocity modulation type, the generator (10) being configured so that substantially all the modulation energy generated by piezo-electric crystals (60) is transformed into vibration of the nozzle (34). The generator preferably also includes an internal closure mechanism (70) which blocks off the nozzle (34) when the generator is not in operation, but which is de-coupled from the modulation process when the generator is operating.
