Abstract: A shock absorber which is responsive to changes in inertia from turning, accelerating or stopping, the change in inertia blocking flow of damping fluid in the normal reactive direction and allowing flow in the opposite direction, the flow in the opposite or corrective direction being propelled by road surface features, such that the shock absorber will level the vehicle and over-correct against the effects of the inertia. Piston travel in the corrective direction is limited as the piston approaches either end of the cylinder by providing a flow path around the piston to prevent the piston contacting the end of the cylinder.
