A self-regulated actuator is disclosed having a shape-memory element which is heated preferably by passing electrical current therethrough and having a reset mechanism including a circuit-breaking mechanism. The shape-memory element provides the force to retract the actuator when heated. The reset mechanism utilizes a spring-biased latch plunger that resets the actuator as soon as it has retracted a specific distance. The reset mechanism also acts as a circuit-breaking mechanism to electrically interrupt current heating the shape-memory element. The rese...
A self-regulated actuator comprising: a shape-memory element capable of being longitudinally expanded when in its martensitic state and capable of being longitudinally recovered when in its austenitic state, said element capable of dimensional recovery when heated from said martensitic state to said austenitic state, said element having a first end and a second end along the longitudinal axis thereof; a plunger located at the first end of said element; a latch means connecting said plunger to said first end of said element when said element is longitudin...
