Abstract
A fluidic control valve includes a piezostack actuator, a seal plate, and an orifice plate including a plurality of orifices. The piezostack actuator is configured to move the seal plate along a longitudinal axis between a closed position, in which the seal plate seals the orifices of the orifice plate and closes the valve, and an open position, in which the seal plate is displaced from the orifice plate to open the valve.
