Abstract

An electrical energy generator comprising a housing having a longitudinal axis and opposite 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 engaged with the electromagnetically active mass, and at least one spring positioned between at least one of an end of the housing and an end of the body, or between an end of the body and the electrically conductive material.

Claims

1. An electrical energy generator comprising:

a housing having a longitudinal axis and opposite ends;

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

an electrically conductive material positioned within the housing;

a body engaged with the electromagnetically active mass, wherein the body comprises a shaft and spring stops at opposite ends; and

a first spring positioned between a first end of the body and the electrically conductive material and a second spring positioned between a second end of the body and the electrically conductive material.

2. The electrical energy generator of claim 1, wherein the generator comprises a third spring positioned between a first end of the housing and a first end of the body and a fourth spring positioned between a second end of the housing and a second end of the body.

3. The electrical energy generator of claim 1, further comprising at least one secondary spring positioned between an end of the body and an end of the housing, wherein the secondary spring has a nonlinear spring coefficient.

4. The electrical energy generator of claim 2, wherein at least one of the first, second, third, or fourth springs has a nonlinear spring coefficient.

5. The electrical energy generator of claim 1, wherein at least a portion of the shaft of the body comprises a permanent magnet.

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

7. The electrical energy generator of claim 6, wherein the electrically conductive material comprises at least one induction coil.

8. The electrical energy generator of claim 7, wherein said at least one spring comprises a coil spring.

9. The electrical energy generator of claim 8, wherein said at least one coil spring comprises a compression spring.

10. The electrical energy generator of claim 8, wherein said at least one coil spring comprises an extension spring.

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

12. The electrical energy generator of claim 1, wherein the spring stops of the body are 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.

13. The electrical energy generator of claim 1, wherein the spring stops of the body are adapted to minimize motion retardation during movement of the electromagnetically active mass and body within the housing.

14. 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.

15. 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.

16. The electrical energy generator of claim 2, wherein the third and fourth springs are pre-compressed within the housing.

17. The electrical energy generator of claim 2, wherein the third and fourth springs are pre-extended within the housing.

18. The electrical energy generator of claim 1, wherein the first and second springs are pre-compressed within the housing.

19. The electrical energy generator of claim 1, wherein the first and second springs are pre-extended within the housing.

20. The electrical energy generator of claim 2, wherein the first, second, third and fourth springs are pre-compressed within the housing.

21. The electrical energy generator of claim 2, wherein the first, second, third and fourth springs are pre-extended within the housing.

22. The electrical energy generator of claim 1, further comprising a guide to minimize or substantially prevent the non-reciprocating motion of said electromagnetically active mass within said housing.

23. The electrical energy generator of claim 22, wherein the guide comprises a rod which passes through the center of the electromagnetically active mass and is engaged with the ends of the housing.

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