Abstract

PURPOSE:To provide effective pressurization of fluid for improving the pumping efficiency, by forming working chambers on both sides of a diaphragm. CONSTITUTION:When a coil 2 is energized, diaphragm 10 reciprocatingly vibrates to the axial direction in accordance with a movable piece 3, which can change the volume of working chambers 21, 21a formed on both sides of the diaphragm 10 to take air in the working chamber 21 from a suction port 12a through a fluid passage 24, communicating hole 25, suction chamber 17a and suction valve 13. The working 21 is then effectively pressurized to discharge the air through a discharge valve 14, discharge chamber 18a and discharge port 20 made on a lid 23. Air taken in the working chamber 21a, on the other hand, through a suction port 12a, space for the coil 2 and movable piece 3 and a suction valve 13a, pressurize the chamber for discharging through a discharge valve 14a, fluid passage 24a, communicating hole 25a and discharge chamber 18a. This system thus can provide the efficient pumping action.
