ABSTRACT:
An impulse fluid jet apparatus having pulse generating circuitry for an impulse jet. The circuitry generates driving a longer pulse exciting the resonant frequency of the jet and a shorter pulse for exciting a higher harmonic frequency of the jet. The longer pulse changes the state of energization of the transducer in the jet to eject a droplet of fluid and the shorter pulse changes the state of energization so as to break off the tail of the droplet.
