Abstract
A vibration isolator (10) includes an outer housing (14) with an inner housing (16) supported for reciprocation therein. The inner housing (16) includes an elastomeric spring (32) supporting a sleeve or inner cylinder (30) with a passage (44) extending therethrough interconnecting a pair of spaced apart chambers (40,42) defined between the housings (14, 16). A tuning mass including liquid is disposed in the chambers (40,42) and the passage (44). The inner housing (16) functions as a piston to move the tuning mass through the inner cylinder (30) between the chambers (40,42) and generate amplified counter-inertial forces to cancel vibration.
