HYDRAULIC SYSTEM WITH PRIORITY CONTROL ABSTRACT OF THE DISCLOSURE A hydraulic system includes a pressure and flow com- pensated pump, a source of pilot fluid under pressure, a plurality of hydraulic circuits each including a work per- forming device, and a plurality of controls, one for each circuit. Each control includes a pilot operated flow valve for connecting the associated work performing device to the pump and an operator positioned valve connected to the pilot source for selectively directing pilot fluid to the corre- sponding flow valve. The work performing devices and the flow valves are connected in parallel. The system includes a supply margin valve having pressure responsive surfaces respectively connected to the pump and to the work performing devices for providing a control signal to the pump to cause the same to supply fluid at a pressure equal to the pressure required by the work performing devices plus a predetermined margin and a first demand margin valve having pressure re- sponsive surfaces respectively connected to the pump and to the work performing devices for decreasing the pressure of pilot fluid directed to some, but not all, of the operator positioned valves when the predetermined margin is not met. - 1 -
