回转气缸在有限的旋转范围内输出扭矩。大多数气缸的转角小于360°,但是,如果由于使用上的需要,也有的气缸设计成可实现其回转轴转动几转的。回转气缸与气马达不同,气马达在任意的旋转范围内输出高速低扭矩,而回转气缸是在特定的旋转范围内产生瞬时的低速大扭矩。回转气缸中的机械止动器能使气缸实现 The rotary cylinder outputs torque over a limited range of rotation. Most cylinders have a rotation angle of less than 360 °, however, some cylinders are designed to rotate a few revolutions of their rotary shaft if required by the user. Swing cylinders, unlike gas motors, have high-speed, low-torque air motors that deliver high-speed, low-torque over any range of rotation, while rotary cylinders produce low-speed high-torque moments of instantaneous speed over a specified range of rotation. The mechanical stop in the rotary cylinder enables the cylinder to be realized
