摘要： A rotary type hydraulic servo-mechanism constructed with a hollow-cylindrical casing, an input shaft extending through the casing, a driven output member slidably mounted on the casing, a servo-valve mechanism formed in the surface of the input shaft which slides on the driven output member, a hydraulic fluid chamber to generate a resisting torque against rotational force of the input shaft, and a passage to connect this hydraulic fluid chamber with the servo-valve mechanism, and hydraulic drive chambers defined by a space between the inner wall of the hollow cylindrical casing and the outer periphery of the driven output member.
