<p>A hydraulic power steering system has a servo valve which is arranged between the delivery and suction side of a hydraulic pump. The servo valve is open in the central or normal position and controls the pressure to at least one connection of a hydraulic servomotor. When an operating element of the power steering system is actuated, the servomotor serves to generate a servo positioning force which facilitates the adjustment of the operating element. The hydraulic pump has a drive which can be switched-off, or can be switched over to an extremely low capacity or standby operation, when no servo positioning force is required.</p> |
