のバイモルフ型圧電素子の揺動変位により開閉制
御されるノズルとからなる切換弁において、前記
バイモルフ型圧電素子の中間材であるシム材を磁
性体で構成し、かつ該圧電素子のノズル側端部に
対応して永久磁石もしくは電磁石を移動可能に配
設したことを特徴とする切換弁。 In a switching valve comprising a cantilever-supported bimorph piezoelectric element and a nozzle whose opening and closing are controlled by the swinging displacement of the bimorph piezoelectric element, a shim material that is an intermediate material of the bimorph piezoelectric element is made of a magnetic material. A switching valve characterized in that a permanent magnet or an electromagnet is movably disposed corresponding to the nozzle side end of the piezoelectric element.
