Abstract

A servo valve (100) comprises a first spool (108a) extending along a first spool axis (110a), a second spool (108b) extending along a second spool axis (110b), a first piezoelectric actuator (112a), and a second piezoelectric actuator (112b). The first piezoelectric actuator (112a) is operatively connected to the first spool (108a) for translating the first spool (108a) in response to a voltage applied thereto. The second piezoelectric actuator (112b) is operatively connected to the second spool (108b) for translating the second spool (108b) in response to a voltage applied thereto.
