Abstract: A vibration isolator for connecting a first body and a second body includes a housing having a first chamber (22) , a second chamber (26) , and a port (24) connecting the first chamber (22) to the second chamber (26) and permitting fluid (34) to flow between the first chamber (22) and the second chamber (26). The first and second chambers (22), (26) and the port (24) defining a fluid reservoir (27) . The isolator (10) includes a gas-to-fluid accumulator (30) in fluid communication with the fluid reservoir (27) through a first one-way valve (140) and a second one-way valve (142) . The first one-way valve (140) allows fluid (34) to pass only from the fluid reservoir (27) to the accumulator (30) and the second one-way valve (142) allows fluid (34) to pass only from the accumulator (30) to the fluid reservoir (27). At least one of the first and second one-way valves (140), (142) being preloaded to a predetermined force to permit fluid flow through the at least one-way valve (140), (142) only when fluid pressure exceeds the predetermined force.

Abstract: A tunable vibration isolator shown in figure 8 with active tuning elements having a housing, fluid chamber, and at least one tuning port. A piston is resiliently disposed within the housing. A vibration isolation fluid is disposed within the fluid chambers and the tuning ports. The tunable vibration isolator may employ either a solid tuning mass approach or a liquid tuning mass approach. The active vibration elements are preferably solid-state actuators.
