ABSTRACT:
The invention relates to a hydraulic steering system of the type having a servomotor controlled by a steerable valve assembly which directs metered quantities of pressurized fluid to the servomotor and has a feedback arrangement for stopping the flow of fluid when the steering motion is stopped. The system involves an arrangement wherein the metering unit is arranged downstream from the servomotor and an auxiliary valve is provided for automatically accommodating normal conditions as well as emergency pump failure conditions and overpressure conditions caused by the servomotor reaching an extreme end position in the operation thereof.
