Abstract

A vibration isolator can include an upper housing defining an upper fluid chamber; a lower housing defining a lower fluid chamber; a piston resiliently coupled to the upper housing with an upper elastomer member, the piston being resiliently coupled to the lower housing with a lower elastomer member; a tuning passage associated with the piston; and a tuning fluid disposed within the upper fluid chamber, the lower fluid chamber, and the tuning passage, the tuning fluid comprising a polytungstate.
