Abstract

A failsafe actuator is provided for returning an actuator driven element to a failsafe position in case of a failure condition. The actuator (102) includes a drive assembly (303) for driving a plunger (318) from a first plunger position to a second plunger position. The actuator additionally includes a stored energy element (509) for driving the plunger from the second plunger position to the first plunger position on the occurrence of the failure condition, wherein the actuator driven element is responsive to the plunger such that the actuator drive element is driven to the failsafe position when the plunger is driven to the first position.
