Abstract
A double acting mechanical shock isolator that includes a stack of friction springs contained within a housing. The stack is retained between the end walls of the housing by a pair of opposed slides. A sleeve passes through the stack and the ends of the sleeve are contained within opposing slides. The ends of the sleeve are connected to the slides by lost motion devices so that the sleeve is engaged by one of the containing slides when the sleeve moves toward the opposing slide and releases the slide when the sleeve moves in the opposite direction so that the stack is loaded in compression when the sleeve is moved axially in either direction.
