Abstract: All but the circle drive motor of the implement actuators of a motor grader are divided into two groups each consisting of those which need not be operated simultaneously. The power system has three fixed displacement pumps for driving the circle drive motor via a circle control valve and the two implement actuator groups via respective implement control valve arrangements of carry-over parallel configurations. One of the pumps is connected to the two implement control valve arrangements via a restriction and a flow divider. A first demand valve controls communication between the other two pumps and the implement control valve arrangements in response to the pressure differential across the restriction, maintaining constant fluid flow to the valve arrangements regardless of engine speed or the loads on the implement actuators. A second demand valve likewise responds to a pressure differential across another restriction formed in a conduit communicating the first demand valve and the carry-over ports of the implement control valve arrangements with the circle control valve, maintaining constant fluid flow thereto.

Abstract: A control system for a variable displacement pump which powers a load actuator via a selector valve and which has its displacement varied by a pump actuator of the single-acting type. The system includes a load-sensing control valve for selectively communicating the pump actuator with a pressurized fluid source or with a fluid drain in accordance with a differential between the sum of the pump output pressure and the pump actuator pressure and the sum of the load actuator pressure and the force of a spring. Also included is a normally open, cutoff control valve, connected serially with the load-sensing control valve, for placing the pump actuator in communication with a fluid drain in response to the sum of the pump output pressure and pump actuator pressure acting against the force of a spring.
