する圧電ポンプ。 A pump section consisting of a pump chamber with check valves at each end and a cylinder formed in the side wall portion, and a piston slidably fitted into the cylinder is installed below the lower limit oil level in the oil tank, and is cantilevered. In the piezoelectric pump, the piezoelectric vibrator supported by the piston is disposed above the upper limit oil level, and the movement of the vibrating end of the piezoelectric vibrator is transmitted to the piston by a joint member. A partition wall that partitions the internal space of the oil tank is formed with a window extending over at least both a position higher than the upper limit oil level and a position lower than the lower limit oil level, and the window is blocked by a filter medium. Piezoelectric pump.
