It is vibrated and the fluid is sucked through the suction side check valve 3 from the suction port 6 by this cooperative vibration.
The sucked fluid is discharged from the discharge port 7 through the discharge side check valve 4. As a result, the ejection pressure increases in proportion to the number of piezoelectric vibrators 2, and the ejection amount also increases in proportion to the number of piezoelectric vibrators 2.
