FLUID JETTING DEVICE AND METHOD

PURPOSE: To make the ejection speed of ink droplets ejected from an ink jet head almost constant over a wide range of an ejection repeating rate. CONSTITUTION: A pressure chamber 22 is connected to a manifold 12 by an inlet channel 18 and connected to an orifice 14 by an outlet channel 28. A transdu...

Zusammenfassung:	PURPOSE: To make the ejection speed of ink droplets ejected from an ink jet head almost constant over a wide range of an ejection repeating rate. CONSTITUTION: A pressure chamber 22 is connected to a manifold 12 by an inlet channel 18 and connected to an orifice 14 by an outlet channel 28. A transducer driver 36 generates energy input and the transducer 32 connected to the pressure chamber generates a meniscus in the orifice corresponding to the energy input. The spectrum energy distribution of this energy input is conc. to the vicinity of the main resonance frequency of a fluid and lowers substantially in the vicinity of the resonance frequency of the inlet and outlet channels.
