MANUALLY ACTUATED HYDRAULIC CIRCUIT FOR RAM AIR TURBINE (RAT) RESTOW

A ram air turbine (RAT) restow system (100) includes an actuator assembly (26) with a piston (42) interposed between an upper fluid compartment (53) and a lower fluid compartment (52). The actuator assembly (26) is configured to selectively move the piston (42) between a deployed position and a stowed position. A hydraulic restow circuit is interposed between the actuator assembly (26) and a hydraulic fluid system that is configured to output fluid. The hydraulic restow circuit includes a restow valve configured to operate in a first position that establishes a first fluid path to deliver the fluid to the upper fluid compartment and a second position that establishes a second fluid path to deliver the fluid to the lower fluid compartment.
