摘要：A fluid control device includes a piezoelectric bender (48a, 48b) co-operating with an impacting member (30) to deform a membrane (24) over a valve seat (29) upon energisation or de-energisation for achieving desired rapid and accurate contrrol to fluids under pressure in a variety of different applications, such as, computer printing, fluidics, etc. The bender (48a 48b) as well as the impacting member (30) are each advantageously isolated from the fluid.
