Abstract
A hermetically sealed damper assembly includes a sealed damper housing, a plunger, and a load transferring member coupled to the plunger. The sealed damper housing includes a body having a cavity and a resistive flow path defined therein. The cavity and resistive flow path are filled with a viscous fluid. The body includes a plurality of springs integrally formed therein. The plunger is disposed within the cavity, and separates the cavity into a first control volume and a second control volume. The resistive flow path provides fluid communication between the first and second control volumes. The plunger is coupled to the damper housing by the plurality of springs such that the springs provide a restorative force to the plunger. The load transferring member is configured to transmit mechanical loads to the plunger.
