Abstract

A linear actuator includes a fixed first end, a second end movable linearly along a central axis of the actuator, an inner cylinder configured to urge axial movement of the second end, and a piston assembly including a piston rod located inside of the inner cylinder. One or more locking pawls are located in pawl openings in the piston rod. The one or more locking pawls are selectably engagable with the inner cylinder to prevent relative motion of the piston rod and the inner cylinder. A lockbolt selectably releases the one or more locking pawls from engagement with the inner cylinder and includes an antilock pin engagable with a pawl opening in the one or more locking pawls to urge the one or more locking pawls away from the inner cylinder with axial movement of the lockbolt.
