Definitions

  • FIG. 4 is a schematic cross-sectional drawing of a magnetic spring actuator comprising a magnetic ring and a magnetizable piston slidably disposed inside of the ring;
  • FIG. 2 represents a simple magnetic spring 20 comprised of a magnetic ring 22 and an iron piston 24 that protrudes from ring 22 . While in FIG. 1 the piston was magnetic and the ring was non-magnetic, in FIG. 2 the ring is magnetic and the piston is non-magnetic. An initial applied force causes piston 24 to become displaced from its original starting position (the starting position resulting from the magnetic force created by the ring on the piston). Subsequently, the magnetic return force induced by magnetic ring 22 causes piston 24 to return to its starting point.
