1. A magnetic spring actuator device comprising:

  • a) a piston and a ring arranged such that one of said piston and ring is a fixed part and the other is a moving part;

    b) a non-magnetic holding cylinder having each of said fixed and moving parts disposed therein;

    wherein at least one of said fixed and moving parts is magnetic and wherein due to a magnetic force caused by at least one of said fixed and moving parts, said moving part is initially located in a first position with respect to said fixed part, and wherein upon application of an outside force on said magnetic spring actuator, said moving part moves to a second position with respect to said fixed part, such that said magnetic force produces a return force causing said moving part to return to said first position with respect to said fixed part.
