摘要： The invention relates to a hydraulic steering system architecture comprising at least one steering control actuator having chambers connected to the outlets of a directional-control valve, an accumulator, and an electrically-driven pump unit associated with an emergency supply. The hydraulic system also comprises a general selector arranged, in a normal mode of operation, to connect the feed port of the directional-control valve to a pressure-generator device and the return port of the directional-control valve to a main supply associated with the pressure-generator device, while also ensuring that the emergency supply is filled, and in an alternate mode of operation, to connect the feed port of the directional-control valve to the accumulator.

摘要： The invention relates to an architecture for a hydraulic steering control system including at least one actuator; the hydraulic system comprises a directional-control valve connected to a pressure-generator device and to an associated main supply, the hydraulic system further comprising a reversible electrically-driven pump unit having two ports and being fitted with a general selector arranged, in a normal mode of operation, to put the chambers of the actuator into communication with the directional-control valve, and in an alternate mode of operation to put the chambers of the actuator into communication with the ports of the pump unit. A compensation device makes it possible in the alternate mode to compensate for any flow differential between the flow drawn in by the pump unit from one of the chambers of the actuator and the flow delivered by the pump unit into the other chamber of the actuator.
