WebThe trim actuator, located at the lower portion of shaft 9, comprises a pair of housings 22 and 23 secured together by cap screws 24. The housing '22 is attached to bearing housing 15 by cap screws 25. A reversible motor 26 is attached to housing 23 and is drivingly connected to a reduction gear 27 in said housing through a magnetic clutch 2S. WebThe actuators convert hydraulic pressure into control surface movements. The electro-hydraulic servo valves control the movement of the actuators. The pilot's movement of a control causes the mechanical circuit to open the matching servo valve in the hydraulic circuit. The hydraulic circuit powers the actuators which then move the control surfaces.
