Abstract
A quick-return electro-mechanical actuator ( ) broadly includes a cocking solenoid ( ) and a holding solenoid ( ). Each of the solenoids has an armature ( ) and a rod ( ). The rods are adapted to contact one another when the actuator is energized. However, after the second rod has been moved to its extended position, the cocking coil is de-energized. The mass of the first rod and first armature is thereafter uncoupled and separated from the mass of the second rod and second armature such that when the second coil is subsequently de-energized, a spring ( ) will expand to quickly move the second rod from its extended position to its retracted position
