Abstract
Embodiments of three parameter isolators including rolling seal damper assemblies are provided. In one embodiment, the three parameter isolator includes first and second isolator end portions, which are opposed along a working axis. A main spring and a tuning spring are mechanically coupled in parallel between the first and second isolator end portions. A rolling seal damper assembly is further mechanically coupled between the first and second isolator end portions in parallel with the main spring and in series with the tuning spring. The rolling seal damper assembly includes a first hydraulic chamber, a second hydraulic chamber fluidly coupled to the first hydraulic chamber, and first and second rolling diaphragm seals partially bounding the first and second hydraulic chambers, respectively. In certain implementations, the rolling seal damper assembly also contains a thermal compensator piston to which the first rolling diaphragm seal is attached.
