Isolators including magnetically-assisted thermal compensation devices

摘要

Embodiments of isolators including magnetically-assisted thermal compensation devices are provided, as are embodiments of magnetically-assisted thermal compensation devices. In one embodiment, the isolator includes a damper assembly and a magnetically-assisted thermal compensator (“TC”). The magnetically-assisted TC includes, in turn, a TC chamber fluidly coupled to the damper assembly and configured to exchange damping fluid therewith. A TC piston is slidably disposed within the TC chamber and exposed to damping fluid when the TC chamber is filled therewith. A TC bellows is sealingly coupled to the TC piston and exerts a resilient bias force thereon. A magnetic preload system is further coupled to the TC piston and exerts a magnetic bias force thereon, which combines with the resilient bias force provided by the TC bellows to impart the magnetically-assisted TC with a predetermined pressure profile over the operative temperature range of the isolator.
