Abstract
A dual bellows system and method that includes a main bellows which interacts with a thermally compensating bellows, whereby interaction of the main bellows with the thermally compensating bellows results in a transfer of force and/or displacement that is insensitive to temperature changes.
Claims16
A bellows system, comprising:
- a main bellows containing a first fluid, the main bellows interacting with a thermally compensating bellows containing a second fluid isolated from the first fluid, whereby interaction of the main bellows with the thermally compensating bellows results in a transfer of force and displacement that is insensitive to temperature changes in which the system includes a plurality of bellows of different cross-sections, the bellows system further comprising an activator which transmits a mechanical force and/or displacement into the bellows system.
A bellows system, comprising:
- a main bellows containing a first fluid which interacts with a thermally compensating bellows containing a second fluid, whereby interaction of the main bellows with thermally compensating bellows results in a transfer of force and displacement that is insensitive to temperature changes in which the system includes a plurality of bellows of different cross-sections, the cross sections being optionally cylindrical, the bellows system further comprising an activator which transmits a mechanical force and/or displacement into the bellows system, wherein the first liquid has different thermal properties than the second liquid.
A bellows system, comprising:
- a main bellows containing a first fluid, the main bellows interacting with a thermally compensating bellows containing a second fluid, whereby interaction of the main bellows with thermally compensating bellows results in a transfer of force and displacement that is insensitive to temperature changes in which the system includes a plurality of bellows of different cross-sections, the cross sections being optionally cylindrical, the bellows system further comprising an activator which transmits a mechanical force and/or displacement into the bellows system, wherein the system comprises a first closed system and a second closed system, whereby the force and/or displacement from the first closed system is transferred to the second closed system.
A bellows system, comprising:
- a main bellows containing a first fluid, the main bellows interacting with a thermally compensating bellows containing a second fluid isolated from the first fluid, whereby interaction of the main bellows with thermally compensating bellows results in a transfer of force and displacement that is insensitive to temperature changes in which a plurality of bellows generate varying forces and generate varying displacements.
A bellows system, comprising:
- a main bellows containing a first fluid, the main bellows interacting with a thermally compensating bellows containing a second fluid isolated from the first fluid, whereby interaction of the main bellows with thermally compensating bellows 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.
A bellows system, comprising:
- a main bellows containing a first fluid, the main bellows interacting with a thermally compensating bellows containing a second fluid isolated from the first fluid, whereby interaction of the main bellows with thermally compensating bellows results in a transfer of force and displacement that is insensitive to temperature changes.
A bellows system, comprising:
- a. a main bellows housing for storage and displacement of a first liquid having a direction of thermal expansion, the housing made of a flexible, liquid-tight material and comprising:
- i. an upper portion,
- ii. a lower portion,
- iii. an outer accordion portion sealingly connected along a periphery with the upper and lower portions, and
- iv. at least one entry/exit port formed on at least one of the portions thereof, and
- b. a temperature compensation device including a second bellows which thermally expands in a direction other than the direction of thermal expansion of the first bellows, comprising:
- i. a second bellows housing;
- ii. a second liquid contained in the second bellows housing;
- iii. a support arrangement for the second bellows housing such that the thermal expansion of the first liquid which causes an expansion of the main bellows at a first expansion rate is mitigated by the thermal expansion of the second liquid at a second expansion rate
- c. at least one secondary bellows in fluidic connection with the main bellows, whereby interaction of the main bellows (a) with the temperature compensation device (b) results in a transfer of force and displacement via the first liquid to the secondary bellows (c) that is insensitive to temperature changes.
