Abstract:
1. A method of locking a linear output member in a retracted position within a linear actuator, the linear output member capable of axial motion within a housing of the linear actuator, the method comprising: rotating a generally tubular rotor disposed within a rotary lock assembly of the actuator to a first rotor position, the rotary lock assembly being constrained from axial motion; and shifting a lock capable of radial displacement within the rotary lock assembly based on rotating the rotor to the first position such that the lock engages a radial groove of the linear output member when the linear output member is in a retracted position; wherein the radial groove of the linear output member includes an axially angled, substantially planar surface; and wherein the lock is configured to include an axially angled surface shaped complimentary to the axially angled, substantially planar surface of the radial groove.
