Abstract

A magnetic spring actuator comprising a ring (90), a piston (92) movably disposed inside of the ring, and a non-magnetic holding cylinder (94). At least one of the ring and the piston is magnetic. Due to a magnetic force caused by at least one of the ring and the piston, the piston is initially located in a first position with respect to the ring. Application of an outside force results in movement of the piston to a second position with respect to the ring. The magnetic force produces a return force for causing the piston to return to the tirst position with respect to the ring. Alternatively, the piston can be fixed and the ring can be adapted for moving with respect to the piston in a similar manner. A bi-metal coil spring (148) may be wound around the piston.
