したことを特徴とする流量制御弁。 A valve chamber to which an inflow pipe and an outflow pipe of the controlled fluid are connected, a valve seat provided in the outflow pipe, and a valve seat disposed on the valve chamber side with respect to the valve seat, with the tip thereof close to the opening of the valve seat. A so-called bimorph type piezoelectric element that warps in the thickness direction when a voltage is applied, and a drive plate with the valve body attached to the center. Both ends of the resulting curved surface in a direction perpendicular to the generatrix are tiltably supported, and a bias voltage for determining the zero point of the flow rate and a control voltage in the opposite direction are superimposed and applied to the drive plate. A flow control valve characterized in that the valve body closes an opening of a valve seat when the control voltage is zero.
