Abstract
PURPOSE:To reduce an influence by a dynamic pressure of fluid while increasing the displacement of a valve by driving it by displacement units which support the peripheral edge part having a play of a pair of plate-shaped unimorph elements opposed to each other and displaced in a reverse direction to each other. CONSTITUTION:A pair of unimorph elements 10, 11 and 12, 13 are opposed to each other and supported having a play to supporters 14, 15 so as to flex in a reverse direction to each other, forming displacement units 16, 17. The unimorph element 13 fixes its central part to a bottom cover 41 by an adjusting screw thread 42, and the unimorph element 10 connects its central part to a valve unit 26 through a pressure balance piston 28. When voltage is applied, the unimorph element flexes in the plate thickness direction. The unimorph element is supported to the supporters 14, 15 having a play, smoothly flexing. While the unimorph element, being supported in its peripheral edge part, provides the large rigidity, being prevented from easily receiving an influence by a dynamic pressure of fluid.
