Abstract
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).
