Abstract: A self-contained pneumatic anti-sway assist vehicle body roll control system to supplement existing vehicle suspension by means of sharing load support primary and secondary volumetric gas chamber pressures for soft ride over normal, level road surfaces; then by blocking said secondary gas chambers at load side of vehicle to summarily increase spring rate within its primary load support gas chamber for increased vehicle body suspension support during lateral forces encountered with right and left turns and/or with vehicle body lean when off-camber.

Abstract: An integral self-leveling gas shock strut with dual spring rates as a structural load support between a vehicle chassis and wheel. When the vehicle is driving at an inclined longitudinal pitch a gravity sensitive device within the strut governs a pilot valve which opens to allow a pressure input signal from strut piston compression deflection to close a high flow volume slave valve located between primary and secondary volumetric chambers, trapping gases within the primary chamber to provide a hard spring rate for the strut mounted on the vehicle's downhill side. Contrarily, a similar valve sequence in a companion strut mounted on the vehicle's uphill side opens gas flow communication to combine its primary and secondary chamber volumes, thus providing a soft spring rate and consequent leveling effect of the vehicle using only the pumping action of the strut pistons as a power source, requiring neither external power nor inputs.
