A servo actuator 1 is provided. The servo actuator 1 comprises: an actuator housing 4; an actuator member 2 located within the actuator housing 4; and at least one spool 8 located in a cavity 6 formed within the actuator housing 4. The housing 4 also comprises a first set of internal ports including an inlet port P, an outlet port T and a pair of control ports S1, S2, the inlet port P is connected to a first pressurised supply; and a second set of internal ports comprising an inlet port P, an outlet port T; and a pair of control ports S1, S2, the inlet port P is connected to a second pressurised supply. In use, movement of the spool 8 alters the flow path of fluid through the first and second set of internal ports to control the movement of the actuator member 2. |
