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.
Isolateur de vibration réglable, comprenant un boîtier, une chambre de fluide et au moins un passage de réglage. Un ensemble de piston est disposé de façon élastique à l'intérieur du boîtier. Un fluide d'isolation aux vibrations est autorisé à s'écouler depuis les chambres de fluide à travers le passage de réglage. Une vanne de dosage est actionnée vers le haut ou vers le bas dans le but de modifier le diamètre effectif du passage de réglage, entraînant une variation de la fréquence d'isolation.
