Patent ID: 8444121

Claim:
A system for damping vibrations from a payload, the system comprising: a plurality of isolation struts, each isolation strut of the plurality of isolation struts comprising: a cylindrical outer housing comprising a deformable material; a flexure extending from an end of the outer housing to couple the isolation strut to the payload, the flexure having a first end and a second end, wherein the flexure first end is attached to the payload to thereby receive vibration therefrom, wherein the flexure second end is coupled to one or more damping components disposed within the outer housing, and wherein the flexure comprises and elastic material; a bellows, a piston, and an end cap, the bellows comprising a first end and a second end, the piston comprising a first end and a second end, and the end cap comprising an axially extending flange, wherein the axially extending flange is adapted to attach to the flexure second end, and wherein the bellows second end is coupled to the piston first end, thereby defining a chamber that is sealed at one end defined by an inner surface of the bellows, the end cap, and the piston; and a damping annulus extending through the piston the damping annulus comprising a gas inlet for receiving a gas from the chamber and a gas outlet through which the gas is expelled from the isolation strut, the gas inlet providing flow communication between the chamber and the damping annulus, wherein the damping annulus comprises a channel extending between the gas inlet and the gas outlet, and wherein the damping annulus is formed in a shaft that is inserted into and fixed within a passage formed through the piston; a single gas line comprising tubing or piping sealingly coupled to each isolation strut of the plurality of isolation struts with a plurality of gas line connectors, each gas line connector of the plurality of gas line connectors sealingly coupling a respective isolation strut of the plurality of isolation struts to the single gas line so that the gas line is in fluid communication with the gas outlet of each respective isolation strut of the plurality of isolation struts, each gas line connector of the plurality of gas line connectors being coupled, at each isolation strut of the plurality of isolation struts, to an outer flange of the piston that extends radially outward relative to the gas outlet, thereby preventing relative movement between the gas line connector and the gas outlet; a single mounting structure to which the single gas line is mounted; and a plurality of strut brackets mounted to the single mounting structure and having each isolation strut of the plurality of isolation struts mounted thereto, wherein each gas line connector of the plurality of gas line connects mounts each isolation strut of the plurality of isolation struts to each strut bracket of the plurality of strut brackets; wherein the system is hermetically sealed to contain a gas therein.
