摘要： A RECIRCULATING FLUID SUPPLY SYSTEM INCLUDES A CONTROL DEVICE FOR CONTROLLING FLOW IN A BY-PASS PORTION OF THE SYSTEM TO PROVIDE A MEASURE OF THE RATE OF DELIVERY TO DIESEL ENGINE FUEL INJECTORS, BURNERS, OR OTHER FLUID-CONSUMPTION EQUIPMENT. A PUMP SUPPLIES FLUID FOR A RESERVOIR TO A MAIN CONDUIT AND TO THE BY-PASS CONDUIT FLUID ID WITHDRAWN FROM THE MAIN CONDUIT THROUGH A BRANCH CONDUIT TO FLUID CONSUMING EQUIPMENT. THE MAIN CONDUIT RETURN UNUSED FLUID TO THE RESERVOIR. A CONTROL DEVICE, WHICH IS RESPONSIVE TO THE RATE OF FLUID FLOW IN THE MAIN CONDUIT ON BOTH SIDES OF THE BRANCH CONDUIT, CONTROLS THE RATE FLOW IN THE BY-PASS CONDUIT. FLUID FLOW IN THE BY-PASS CONDUIT IS SUPPLIED TO THE MAIN CONDUIT AT A SUITABLE POINT WHEREBY FLUID FLOW THROUGH THE BY-PASS CONDUIT INTO THE MAIN CONDUIT IS AT A RATE EQUAL TO THE RATE OF FLUID FLOW FROM THE MAIN CONDUIT TO THE FLUID CONSUMPTION EQUIPMENT. IN THE MANNER, A MEASURE OF THE FLUID ADDED THROUGH THE BY-PASS CONDUIT IS A MEASURE OF THE FLUID CONSUMED.
