Réduction of Flow Pulsation <Example of Combination with Piezoelectric Micro Pump> Piezoelectric micro pumps are small-sized, lightweight and slim diaphragm micro pumps driven by piezoelectric élément. By considerably reducing the drive frequency and the drive voltage from the standard operating ranges, a piezoelectric micro pump alone can transfer |j|/min level flows. However, significant pulsation is created at a low flow rate as represented by the blue line in the graph below. By incorporating a micro needle valve on the discharging side of a piezoelectric micro pump, a low flow rate with...
