Abstract

An electrical energy generator including a housing, an electromagnetically active mass positioned within the housing, an electrically conductive material within the housing, a body positioned within the housing wherein the body and the electromagnetically active mass move relative to each other, and at least one spring for imparting restorative forces to the electromagnetically active mass and the body.

Claims

1. An electrical energy generator comprising:

a housing having a longitudinal axis and first and second opposing ends;

an electromagnetically active mass positioned within the housing reciprocally movable along at least a portion of the longitudinal axis;

an electrically conductive material within the housing;

a body positioned within the housing reciprocally movable along at least a portion of the longitudinal axis, wherein the body and the electromagnetically active mass move relative to each other, the body comprising a shaft portion and first and second spring stop portions, the shaft portion being engaged with and between the first and second spring stop portions;

a first spring positioned between the first spring stop portion and the electrically conductive material;

a second spring positioned between the second spring stop portion and the electrically conductive material;

a third spring engaged with the first spring stop portion and the electromagnetically active mass; and

a fourth spring engaged with the second spring stop portion and the electromagnetically active mass.

2. The electrical energy generator of claim 1, further comprising:

a fifth spring positioned between the first end of the housing and the first spring stop portion; and

a sixth spring positioned between the second end of the housing and the second spring stop portion.

3. The electrical energy generator of claim 2, wherein at least one of the fifth and sixth springs has a nonlinear spring coefficient.

4. The electrical energy generator of claim 3, wherein at least one of the first and second springs has a nonlinear spring coefficient.

5. The electrical energy generator of claim 1, further comprising a guide rod extending along the longitudinal axis of the housing and fixed to the opposite ends of the housing.

6. The electrical energy generator of claim 5, wherein the guide rod passes through the shaft portion of the structure and the electromagnetically active mass.

7. The electrical energy generator of claim 1, wherein the housing comprises a cylinder or tube.

8. The electrical energy generator of claim 1, wherein the electrically conductive material comprises at least one induction coil.

9. The electrical energy generator of claim 1, wherein at least one of the springs of the generator comprises a coil spring.

10. The electrical energy generator of claim 9, wherein at least one of the springs of the generator comprises a compression spring.

11. The electrical energy generator of claim 9, wherein at least one of the springs of the generator comprises an extension spring.

12. The electrical energy generator of claim 9, wherein at least one of the springs of the generator comprises a pre-compressed spring.

13. The electrical energy generator of claim 12, wherein at least one of the first, second, fifth and sixth springs comprises a pre-compressed spring.

14. The electrical energy generator of claim 1, wherein the electromagnetically active mass comprises at least one permanent magnet.

15. The electrical energy generator of claim 14, wherein the electromagnetically active mass comprises at least one electromagnetically active mass portion and at least one electromagnetically inactive mass portion.

16. The electrical energy generator of claim 1, wherein the shaft portion is adapted to constrain the movement of the electromagnetically active mass to minimize or substantially prevent non-reciprocating motion of the electromagnetically active mass within the housing.

17. The electrical energy generator of claim 1, wherein the interior of the housing is in communication with the surrounding environment by means of at least one of apertures, holes, vents, slots, or perforations located within the housing.

18. The electrical energy generator of claim 1, wherein the housing comprises a closed structure and an atmosphere within the housing comprises at least one of air, nitrogen, a Nobel gas, mineral oil, vegetable oil, water, saline, partial vacuum, substantial vacuum, a ferrofluid, or combinations thereof.

19. The electrical energy generator of claim 1, further comprising at least one means for adjusting the deflection of at least one of the springs of the generator.
