A mode valve includes a spool axially moveable within a sleeve in response to a control (e.g. hydraulic or electro-mechanical) command. The spool includes channels and lands, and the sleeve comprising ports in fluid communication with a hydraulic fluid supply and ports in connection with control chambers of an actuator responsive to the valve. The valve also includes first drive means for moving the spool, relative to the sleeve, between a first position, and a second position in which fluid flow from the fluid supply to the actuator chambers through the valve is blocked and wherein a fluid path with a first pressure drop is defined in the mode valve for fluid flow between actuator chambers; the mode valve comprising second drive means for moving the spool relative to the sleeve to a third position in which fluid flow from the fluid supply to the actuator chambers is blocked.
A mode valve comprising:
