ABSTRACT:
A linear electromechanical actuator has a spring-loaded plunger disposed in a housing. When a solenoid in the housing is energized, the armature of the solenoid moves linearly and, after some initial "lost" motion, engages and releases the latch mechanism holding the plunger in the housing. The spring associated with the plunger is then free to extend the plunger from the housing. The actuator can be designed so that it is highly immune from unintended actuation due to acceleration of the actuator. The condition of the actuator (e.g., fully cocked or released) can be monitored by switches disposed in the actuator. The actuator can also be constructed to allow manual release as an alternative to release by energization of the solenoid.
