Magnetic spring actuator device
First Claim
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.

Abstract
A magnetic spring actuator comprising a ring, a piston movably disposed inside of the ring, and a-non-magnetic holding cylinder. 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 first 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 may be wound around the piston.
