Abstract
A double acting shock isolator that includes a cylindrical housing having a radially expanded chamber therein. The housing is closed at one end and open at the other end and a connector is mounted at the closed end. A stack of friction rings are mounted in a preloaded condition between the ends of the expanded chamber and a rod passes into the open end of the housing and through the stack. A pair of spaced apart raised flanges are mounted upon the rod that engages either end of the stack. A second connector is mounted upon the distal end of the rod outside of the housing so that the stack of friction rings is further compressed uniformly when either a tensile force or a compressive force is applied to the connectors.
