摘要：A control apparatus is disclosed for permitting simultaneous actuation of aplurality of fluid motors whose combined flow capacity exceeds the available flow rate.The plurality of fluid motors are actuated by a corresponding plurality of open center,pressure- compensated, pneumatically actuated control valves which are connected inseries flow arrangement with a fluid supply having a fixed minimum flow output and amaximum flow rate output. A device is provided to sense the rate of flow for hydraulicfluid exhausting from the series of control valves. The rate of flow sensing devicecontrols a pneumatic pressure regulator that provides a corresponding pressure changein the pneumatic supply pressure provided to a plurality of control valves.
