Abstract (en)
[origin: WO2010091343A2] A piezoelectric valve is provided that includes a valve body includes a plug and a drive body coupled to the valve body and operable to cause the rotatable plug to rotate about a rotational axis. The drive body includes a shaft disposed along the axis, the shaft statically coupled to the plug and rotatably coupled to the drive body. The drive body also includes a rotor assembly disposed about the axis and rotatably coupled to the drive body. The drive body further includes a first piezoelectric actuator disposed about the axis and statically coupled to the drive body, the first piezoelectric actuator configured to frictionally engage an inner surface of the rotor assembly. The drive body additionally includes a second piezoelectric actuator disposed about the axis and statically coupled to the shaft, the second piezoelectric actuator configured to frictionally engage the inner surface of the rotor assembly.
