ABSTRACT:
A vehicle steering system comprises a source of fluid, a hydraulic steering motor actuatable to effect vehicle steering, and a steering control valve in fluid communication with the source of fluid and with the steering motor. The steering control valve is operable to direct fluid from the source of fluid to the steering motor. A metering mechanism is connected in fluid communication with the steering control valve and the steering motor. The metering mechanism is manually operable in accordance with the operator's demand for steering, and a hydraulic system is responsive to demand for steering fluid by the metering means to increase the output flow of the fluid from the source of fluid to the metering means at a pressure sufficient only to effect steering action against a variable load.
