    摘要: A power transmission system includes a linear fluid actuator having a cylinder and a piston, a screw rotatably mounted in the cylinder in an axially fixed position and having a threaded connection with the piston wherein there is some play between the threads, and means arranged to rotate the screw in either direction only when the mechanical load on the piston has counterbalance by corresponding force derived from fluid pressure for movement in both directions.
