Abstract

Perfection in power steering for cars; they are two hydraulic steering circuits, independent of each other, constituted by a steering gear containing a servomotor and a control mechanism for the first steering circuit, as well as by another control mechanism in communication with the steering gear, which goes hydraulically connected with another servomotor acting on the steering linkage for the second steering circuit, characterized in that the first steering circuit carries a pump driven by the vehicle engine, while the pump of the second steering circuit, is driven by the wheels of the vehicle, the corresponding control system being constituted as a combined valve for both steering circuits, by an absolute hydraulic separation, by a piston valve and a slide valve, and because the control system of the second steering circuit reacts when uncouples the installation control of the first circuit d and address.
