Abstract: An apparatus for adjusting the force in a door operator or closer includes a tube rotatable about a longitudinal axis and a coil spring therein connected to door operator/closer. A fixed adjusting screw extends along the longitudinal axis of the housing through the coil spring and a spring collar is threaded onto the adjusting screw and rotatable with the tube. The spring collar bears on the distal end of the spring to vary the spring compression upon rotation of the housing and thereby vary force applied by the door operator or closer. The housing has an opening though which the spring is visible, and the tube has markings indicating the degree of spring compression. An indicator is moveable along and visible outside the housing to indicate the compression of the spring.

Abstract translation: 用于调节门操作者或关闭器中的力的装置包括可围绕纵向轴线旋转的管和连接到门操作者/更近的螺旋弹簧。 固定的调节螺钉通过螺旋弹簧沿着壳体的纵向轴线延伸，并且弹簧套环螺纹连接到调节螺钉上并与管可旋转。 弹簧圈承载在弹簧的远端上，以在壳体旋转时改变弹簧的压缩力，从而改变由门操作者或更近的人施加的力。 壳体具有弹簧可见的开口，并且管具有指示弹簧压缩程度的标记。 指示器可沿外壳移动并且在壳体外部可见，以指示弹簧的压缩。
