Abstract:

An automatic and manual linear reversion control mechanism for a hydraulic servo actuator assembly is disclosed for linearly transferring control between an automatic (fly by wire) control mechanism and a manual control mechanism. A command select mechanism includes two axially aligned pins mounted on a rigid command selector bar, with the first pins slidably mounted in a slot in a control bar of the manual control mechanism and the second pin slidably mounted in a slot in the control bar of the automatic control mechanism so that movement of the command selector bar to displace the two axially aligned pins in their associated slots provides a linear transfer of control of the hydraulic assembly between the manual control and the automatic control.
