What is claimed is:

1. A bellows system (100), comprising: a main bellows (102) which interacts with a thermally compensating bellows (104), whereby interaction of the main bellows (102) with thermally compensating bellows (104) results in a transfer of force and displacement that is insensitive to temperature changes in which the system (100) includes a plurality of bellows (116, 118, 120, 122) of different cross-sections, the cross sections being optionally cylindrical, the bellows system (100) further comprising a crown (140) which transmits a mechanical force (142) and/or displacement (144) into the bellows system.

2. The bellows system of claim 1, in which the thermally compensating bellows rests within a cavity (106) of the main bellows (102).

3. The bellows system of claim 1 , in which the main bellows (102) comprises a first liquid (108), and the thermally compensating bellows (104) comprises a second liquid (110).

4. The bellows system of claim 1 in which the first liquid (108) has different thermal properties than the second liquid (110).

5. The bellows system of claim 1 further comprising at least one tube (112).

6. The bellows system of claim 1 in which at least one tube (112) comprises a tube manifold (114).

7. The bellows system of claim 1 in which at least one tube (112) is in fluid communication with at least one bellows (1 16).

8. The bellows system of claim 1 in which the tube manifold (114) is connected to a plurality bellows (116, 118, 120, 122).

9. The bellows system of claim 1 in which the plurality of bellows (116, 118, 120, 122) are of different cross-sections, the cross sections being optionally cylindrical.

10. The bellows system of claim 1 in which the plurality of bellows (116, 118, 120, 122) generate varying forces (124, 126, 128, 130) and generate varying displacements (132, 134, 136, 138), the varying displacements optionally being linear displacements.

11. The bellows system of claim 1 in which the forces, displacements and cross-sections of the bellows are mathematically dependent on one another.

12. The bellows system of claim 1 in which the system comprises first closed system (146) and a second closed system (148), whereby the force and/or displacement from the first closed system is transferred to the second closed system.

13. The bellows system of claim 12, wherein temperature fluctuations have no or minimal effect on the force and/or displacement produced in the second closed system.

14. A bellows system (100), comprising: a main bellows (102) which interacts with a thermally compensating bellows (104), whereby interaction of the main bellows (102) with thermally compensating bellows (104) results in a transfer of force and displacement that is insensitive to temperature changes in which a plurality of bellows (116, 118, 120, 122) generate varying forces (124, 126, 128, 130) and generate varying displacements (132, 134, 136, 138), the varying displacements optionally being linear displacements.

15. A bellows system (100), comprising: a main bellows (102) which interacts with a thermally compensating bellows (104), whereby interaction of the main bellows (102) with thermally compensating bellows (104) results in a transfer of force and displacement that is insensitive to temperature changes in which the forces, displacements and cross-sections of the bellows being mathematically dependent on one another.

16. A bellows system (100), comprising: a main bellows (102) which interacts with a thermally compensating bellows (104), whereby interaction of the main bellows (102) with thermally compensating bellows (104) results in a transfer of force and displacement that is insensitive to temperature changes.
