ABSTRACT:
The power actuator comprises a housing in which are mounted a motor-driven worm gear and an actuating shaft for controlling the operative condition of a machine element. Rotary motion of the worm gear is transmitted to the actuating shaft by one or more gear wheels and a sector gear which is fixed for angular movement with the actuating shaft. The gear wheel meshes with the sector gear. A force moderating spring is disposed inside and is attached to the housing. The force moderating spring is attached to a link which extends alongside a portion of the sector gear and which is connected to the gear wheel for transmitting the spring force thereto.
