ABSTRACT:
An actuator has a driving piston disposed in a cylinder tube and is interlockable with a driving stem, the driving piston being normally biased resiliently downwardly, but when the driving piston is forced upwardly, it is retained against the resilient force of a retaining device. When the driving piston is forced downwardly, the retaining device is released from its retaining action, allowing the piston to descend rapidly by virtue of the resilient force, the driving piston being connected to a valve body of a valve assembly or the like.
