METHOD AND APPARATUS FOR IMPROVED VIBRATION ISOLATION

摘要

A tunable vibration isolator having a hous-ing, fluid chamber, and at least one tuning passage. A pis-ton assembly is resiliently disposed within the housing. A vibration isolation fluid is allowed to flow from the fluid chambers through the tuning passage. A metering valve is actuated up and down in order to change the effective di-ameter of the tuning passage, resulting in a change to the isolation frequency.
