Abstract

A system is disclosed for controlling the roll of a motor vehicle. The system comprises a hydraulic cylinder arrangement connected between an unsprung portion of the vehicle and a sprung portion of the vehicle. Various seals and ports are arranged within the hydraulic cylinder arrangement, and a volume of hydraulic fluid is disposed in the bore of the cylinder. By selectively preventing hydraulic fluid flow out of the ports, a piston within the cylinder can only move in a direction toward a neutral position within the cylinder, thus providing a self centering action of the suspension.
