A cylinder and piston assembly having damping orifices disposed on a wall of the cylinder is used for impact energy and force reduction. The damping orifices may be of any shape and, therefore, a cylinder and piston may produce variable damping forces and variable resistive forces. A damping orifice may be positioned at any point or location along the length of the cylinder bore. The damping coefficient of the system begins to change at the location of a damping orifice in the cylinder bore. A desired system response, e.g., progressive, regressive, varying, or any combination thereof, etc., may be advantageously obtained by designing the damping orifices to produce falling-rate and/or rising-rate damping coefficients. |
