Abstract
PURPOSE:To make it possible to set the maximum displaced position of a piezo- electric element so that a piezo-electric support member may move, by providing such an arrangement that a flange part of the piezo-electric support member abuts against the maximum displaced position of the piezo-electric element. CONSTITUTION:A unimorph piezo-electric element 24 is provided at the gravitational center position 22' thereof with a projection 34 and a support member 36 as a piezo-electric support member B41 having a circular flange part 35 abutting against the outer surface of the unimorph piezo-electric element 25. With this arrangement, the maximum displacements of the piezo-electric elements 24, 25 are converted into the motion of the piezo-electric support member A36, thereby it is possible to ensure the displacement of a valve element 19 associated with the piezo-electric support member.
