Abstract: A jetting dispenser includes an actuator with a piezoelectric unit that lengthens by a first distance in response to an applied voltage, and an amplifier operatively coupled to the piezoelectric unit. The amplifier includes first and second ends and the second end moves through a second distance, larger than the first distance under the applied voltage. First and second springs are positioned on opposite sides of the piezoelectric unit. The springs are coupled to the piezoelectric unit in a manner that maintains the piezoelectric unit under constant compression. A fluid body includes a movable shaft operatively coupled with the second end of the amplifier and includes a fluid bore and an outlet orifice. The movable shaft is moved by the second end of the amplifier under the applied voltage and jets an amount of fluid from the fluid bore through the outlet orifice.
