FAIL-SAFE ACTUATING SYSTEM

摘要

Described is a fail-safe actuating system, comprising an actuator with an actuator housing and an output element. The output element is couplable to a controlled device. The fail-safe actuating system also comprises a biasing element, coupled to the actuator housing, which gets biased by a movement of the actuator housing in a first predefined direction; a locking device that locks the actuator housing for holding the biasing element in a biased state; and a controller configured to operate the actuator in a first operating mode, in which the actuator housing moves with respect to the output element for biasing the biasing element, and in the second operating mode, in which the output element moves with respect to the actuator housing for moving the controlled device.

1. A fail-safe actuating system comprising:
an actuator with an actuator housing and an output element, wherein the output element is couplable to a controlled device to move the controlled device in conjunction with the output element; a biasing element coupled to the actuator housing, wherein the biasing element is biased by a movement of the actuator housing in a first predefined direction; a locking device to lock the actuator housing for holding the biasing element in a biased state; and a controller configured to:
operate the actuator in a first operating mode, wherein in the first operating mode, the output element is stationary and the actuator housing moves with respect to the output element and in the first predefined direction for biasing the biasing element; andoperate the actuator in a second operating mode, wherein in the second operating mode, the actuator housing is stationary and the output element moves with respect to the actuator housing for moving the controlled device.
