於いて、外バネ、内バネのバネ巻き方向を互に反
対巻きとしたバネ組合せ方で、バネの回転力を低
減し、その合成力をピストン回転防止ストツパー
中心とバネ中心を結ぶ線上と直角（９０°）方向
に発生させてなることを特徴とする油圧サーボモ
ーター圧縮バネ。 In a hydraulic servo motor that opens and closes a steam control valve, the spring combination is such that the winding directions of the outer and inner springs are opposite to each other to reduce the rotational force of the spring and use the resulting force to rotate the piston. A hydraulic servo motor compression spring characterized by being generated in a direction perpendicular (90°) to a line connecting the center of the prevention stopper and the center of the spring.
