Abstract
A fluidic control valve configured to control a flow of fluid through a conduit includes a piezostack actuator, a seal plate having a sealing face, an orifice plate including a plurality of orifices, and a suspension connected to the seal plate. The piezostack actuator is configured to displace the seal plate along a longitudinal axis of the conduit between a closed position, in which the sealing face engages the orifice 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. The suspension is configured to flex and adjust an orientation of the sealing face relative to the orifice plate during movement of the seal plate from the open position to the closed position.
