Abstract
A mounting (20) which provides superior isolation yet which eliminates damaging edge-induced shear strain (ENT) buildup in the elastomer sections (28) and (30) when exposed to high temperatures by having a first elastomer section (28) loaded in compression and a second elastomer section (30) loaded in shear. Exposing the mounting (20) to elevated temperature environments allows the first elastomer section (28) to expand in height and places the second elastomer section (30) in shear to accommodate the height change. The instant invention compensates for fluid and elastomer expansion due to high temperatures by providing a mechanical type compensator (37) which takes up less space and eliminates the pressure loss associated with air-charged compensators (99). Further, a unique combination of fluorinated fluids and polysiloxane polymer enables the mounting (20) to withstand temperatures of greater than 200 deg F. for extended periods of time.
