Abstract

A servo-valve (12) for operating a fluid-operable actuator (5), the servo-valve (12) having a valve member (13) which is movable from an initial position in response to a change of position from a datum position (X) of a part (2) to be moved by said actuator (5) and means for creating a time delay (33,35-34,36) from the commencement of said movement of the valve member (12) from said initial position and to apply a correcting movement to said actuator (5) at the end of said time delay, thereby to return said part to said datum position and the valve member (12) to said initial position.
