Abstract
A laterally disposed cylinder including fluid therein connected between a truck and car body is responsive to lateral forces to provide low damping when relatively low lateral forces are applied and proportionally higher damping as relatively higher lateral forces are applied. The cylinder includes a piston to provide two fluid chambers. The piston includes an opening therein. An element is provided to vary the opening in accordance with the lateral forces.
