摘要:
A fluid actuator characterized by a feedback mechanism for indicating actuator position. The feedback mechanism is driven by the actuator screw shaft, whereby the movements of the feedback mechanism are proportional to the rate and position of the actuator movements. The feedback mechanism and actuator movements may be synchronized so that the extreme end positions of the feedback mechanism will correspond to the fully retracted and extended positions of the actuator. A stroke limiting mechanism may also be provided for preventing the actuator from overstroking the feedback mechanism in the event that they are not properly synchronized.
