ABSTRACT:
In a hydraulic power system having two independent circuits, wherein one circuit has priority over the other circuit, and the priority circuit furnishes a residual flow to the non-priority circuit, a pressure sensing system is provided in the return flow line of the non-priority circuit which causes a directional flow valve to shift and direct the residual flow back to the priority circuit in the event of a leak in the non-priority circuit which results in a loss of pressure in the return line.
