A shape-memory-effect actuator is provided having a shape-memory-alloy spring and a compensator spring. The alloy spring is operatively connected to a concentrically-mounted compensator spring by the use of a protective support housing which surrounds the alloy spring. The actuator includes a shape-memory-alloy spring and a compensator spring that regulates the operating conditions of the shape-memory-alloy spring to a chosen corresponding memory relaxation curve. The memory relaxation curve defines the actuator's operating stress, stroke and life.
1. A shape-memory-effect actuator comprising: a shape-memory-alloy spring having first and second ends; a first actuator termination connected to the second end of the alloy spring; a means; a compensator spring having first and second ends, said compensator spring second end operatively connected in series by said means to said alloy spring first end; and a second actuator termination connected to the first end of the compensator spring; said shape-memory-alloy spring upon recovering with each operating cycle exerting a force throughone of said ...
