Abstract

Improvements in power steering for motor vehicles, with two hydraulic steering circuits independent of each other, consisting of a servomotor in communication with a steering gear and by the corresponding control system for a first steering circuit, as well as by another coupled control system to the steering gear of a second steering circuit that goes in hydraulic communication with a servomotor acting on the steering linkage, characterized in that the two steering circuits carry pumps coupled to the engine of the vehicle, with a power designed to develop approximately half of the maximum power needed for the power steering and because the first steering circuit corresponds to the driving zone and reacts immediately when the steering wheel is operated, and because the second steering circuit corresponds to the parking area and is automatically connected, once the maximum pressure in the first steering circuit has been reached.
