    • A cylinder is installed within a case, and an output shaft and an arm that is integrated thereto and extends in a radial direction are installed within the cylinder. A piston extending in an arc slides and is displaced in a circumferential direction of the cylinder within the cylinder. One end portion of the piston is rotatably connected to the arm. The cylinder is internally provided with a first pressure chamber in which the arm is housed and a second pressure chamber in which the other end portion of the arm is slidably installed. A pressure medium is fed into one of the first and second pressure chambers and discharged from the other, and the output shaft pivots in a rotational direction.
    • 气缸安装在壳体内,并且输出轴和与其一体并且沿径向方向延伸的臂安装在气缸内。 在圆弧中延伸的活塞滑动,并在气缸内的气缸的圆周方向上移位。 活塞的一个端部可旋转地连接到臂上。 气缸在内部设置有第一压力室,臂容纳在该第一压力室中,并且第二压力室中臂的另一端可滑动地安装在该第二压力室中。 压力介质被输送到第一和第二压力室中的一个并且从另一个排出,并且输出轴沿旋转方向枢转。
