PIEZOELECTRIC CONTROL VALVE ABSTRACT OF THE DISCLOSURE A piezoelectric fluid control valve comprises a jet pipe whose position in one axis is controlled by a piezo- electric actuator mechanically connected to the jet pipe. The fluid output from the jet pipe nozzle is normally posi- tioned between a pair of control ports whereby fluid di- vides evenly between the ports. Energization of the piezoelectric actuator by applying a voltage thereto moves the jet pipe thereby increasing the pressure at one port and decreasing the pressure at the other port.
