Abstract
A hydraulic system is provided for a steering system of a vehicle. The hydraulic system includes a pump that supplies pressurized fluid during an operation of the steering system. The hydraulic system also includes an accumulator that is in independent and selective communication with each of the pump and the steering system. When the pump is in the operational state to support the operation of the steering system, some of the fluid may be routed into the accumulator and stored in the accumulator for later use. In the event of failure of the pump when the steering system is in operation, the accumulator provides the required amount of fluid to continue operation of the steering system until charge in the accumulator depletes to a value that is no longer sufficient to support operation of the steering system.
