Patent ID: 8882091

Claim:
A vibration isolator, comprising: a housing having an upper fluid chamber and a lower fluid chamber; a tuning passage; a tuning fluid disposed within the tuning passage, the upper fluid chamber, and the lower fluid chamber; a primary piston resiliently disposed within the housing; an upper pumper piston and a lower pumper piston, the upper pumper piston and the lower pumper piston being coupled to the primary piston, the upper pumper piston and lower pumper piston defining the tuning passage; a linear inductance motor assembly comprising: a magnet member coupled between the upper pumper piston and the lower pumper piston; an inductance coil at least partially surrounding the magnet member; and a control system configured to selectively actuate the magnet member, wherein selective actuation of the magnet member selectively imparts a force upon the upper pumper piston and the lower pumper piston; and wherein a length of the tuning passage is defined by the magnet.
