摘要： A method for driving a droplet ejection device (10) having an actuator (38), including applying a primary drive pulse (1701) to the actuator to case the droplet ejection device to eject a droplet of fluid in a jetting direction, and applying one or more secondary drive pulses (1702-1705) to the actuator which reduce a length of the droplet in the jetting direction without substantially changing a volume of the droplet.

摘要： A fluid droplet ejection device including a body defining a plurality of fluid paths that each include an inlet including a flow restriction, a pumping chamber, and a nozzle opening communicating with the pumping chamber for discharging fluid droplets. An actuator is associated with each pumping chamber. The pumping chamber has a largest dimension that is sufficiently short and the flow restriction provides sufficient flow resistance so as to provide a fluid droplet velocity and/or volume versus frequency response that varies by less than plus or minus 25% over a droplet frequency range of 0 to 40 kHz. Also disclosed are fluid droplet ejection devices in which the ratio of the inlet flow resistance to the pumping chamber flow impedance is between 0.15 and 0.9, the pumping chamber has a time constant for decay of a pressure wave in the pumping chamber that is less than 25 microseconds.
