Abstract

PURPOSE:To perform flow control by altering the timing of voltage to be impressed on a piezoelectric vibrator opening or closing an inlet port and a discharge port and the impressing time both or either side. CONSTITUTION:When a piezoelectric vibrator 1 gets moving in a direction where displacement in a pump is made larger, an inlet port 3 is opened by a piezoelectric vibrator 2 and a discharge port 5 is closed by a piezoelectric vibrator 4. When the piezoelectric vibrator 1 gets moving in a direction where the displacement in the pump is made smaller, the inlet port 3 is closed by the piezoelectric vibrator 2 and the discharge port 5 is opened by the piezoelectric vibrator 4. Accordingly, the timing of voltage to be impressed and the impressing time are altered whereby smooth flow control is performable.
