A vibration isolator (10) for isolating the vibration of two bodies that are connected together is disclosed. The vibration isolator (10) comprises an inner cylinder (16) and a pair of outer housings (12, 14) concentrically bonded together with elastomer structures (18, 20) to form two chambers (22, 26) that are joined by a tuning port (24). The elastomer structures (18, 20) may serve both as the seals for the chambers (22, 26) and the compliant spring members in the isolator (10). The isolator (10) connects to a vibrating body by a spherical bearing (28). The chambers (22, 26) and tuning port (24) are filled with an inviscid fluid (34) and pressurized to prevent cavitation. In certain embodiments, pressure within the isolator (10) is maintained by a volume compensating device (30) connected to the chambers (22, 26) via a small diameter orifice (36).

1. A vibration isolator for connecting a first body and a second body, comprising:a housing having an inner surface defining a fluid volume; a tuning fluid disposed in the fluid volume; an inner cylinder disposed in the fluid volume and having a surface disposed to substantially segregate a portion of the fluid volume, the segregated portion defining a first chamber within the fluid volume; a second chamber having a variable volume; a passage connecting the first chamber to the second chamber and permitting fluid flow from the first chamber to the second chamber wherein the first and second chambers and the passage define a fluid reservoir; a spherical bearing adapted to connect the vibration isolator to the first body; and a gas-to-fluid accumulator having fluid communication with the uppermost portion of the fluid reservoir.
