ABSTRACT A displacement control device for limiting the magnitude of movement between two relatively movable bodies comprises: a first member for securement to one body and a second member for securement to the other body, the first member including a cylinder having a number of viscoelastic discs therein; a solid disc within the cylinder and at each end of the set of viscoelastic discs, a perforated plate fixed within said cylinder and a viscous material between the perforated plate and one of the metal discs, such that upon pressure being exerted up on one metal disc, the viscoelastic discs compress and limit relative movement and upon excess movement of said one metal disc, the second metal disc is moved and extrudes the viscous material through the perforations in said perforated disc so absorbing some of the energy causing the relative movement.
