Device for roll stabilization of a motor vehicle
First Claim
1. A device for reducing the rolling tendency of a motor vehicle with at least one axle that carries at least two wheels, wherein said axle is provided with a roll stabilizer that includes two stabilizer sections which can be turned relative to one another with the aid of a hydraulic device controlled by an electronic control device, with at least one pump that supplies the hydraulic device, and with a valve unit that cooperates with the hydraulic device and influences the turning direction as well as the coupling of the stabilizer sections, and wherein the valve unit contains a changeover valve and a safety valve that can be activated independently of the changeover valve.
