Abstract

The invention relates to a hydraulically assisted steering system for a motor vehicle. Because there is associated with the hydraulic system an electromechanical valve 12 which, in the open state, hydraulically indirectly or directly connects the working chambers 3 , 4, it is possible to dispense with conventional mechanical pressure limiting valves, secondary suction valves and limit stop valves.
