Controlled Demand Priority Hydraulic Circuit Abstract In a hydraulic circuit fluid is passable from a priority valve through control and lockout valves to, for example, a suspension system of a work vehicle or con- trol cylinders of a steering assembly. The lockout valve provides for controllably operating or locking out, for example, the operation of the suspension system where desired. The control valve controllably passes fluid to the suspension system, for example, based upon demand created by operation of the system. The control valve also delivers a signal to the priority valve for maintaining priority of fluid flow from the priority valve to the suspension system. In the circuit, the signal is auto- matically, controllably blocked in response to locking out the operation of the suspension system for preventing the priority valve from maintaining priority fluid flow to the non-operative suspension system. - 15 -
