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