<p>An extrusion damper for interposing between two members to absorb energy of motion which may be induced between the two comprises an outer jacket (1) surrounding a body of a plastically deformable energy absorbing material (3) such as lead and a shaft (2) which moves through the outer jacket to deform the lead during induced motion, and means defining an extrusion orifice between the elements through which the energy absorbing material is forced during induced motion between the two to damp said motion. The body of energy absorbing material is subjected to approximately hydrostatic pressure preferably exceeding the shear yield stress of the energy absorbing material.</p> |
