    摘要: A fail fixed actuator utilizing a rotary cam and servo are provided herein. A rod 10 comprises a piston 11 and a fluid channel 12 extending axially through the rod. A servo orifice 16 at a surface of the rod 10 is in fluid communication with the fluid channel 12. A cam 20 covers a portion of the rod 10 in close fitting relation, and comprises a groove 22. The servo orifice 16 and a portion of the groove 22 combine to form an aperture, movement of at least one of the cam 20 and rod 10 varying the size of the aperture. A piston chamber 13, containing the piston 11, comprises a high pressure chamber 14 and a servo pressure chamber 15, the servo pressure chamber being in fluid communication with the fluid channel 12.
