摘要： A fuel control device 220 includes a restriction 294 and a check valve 292 disposed between a fuel return conduit 236 and a fuel injection supply conduit 227. In operation, fuel from tank 202 flows into the control device via conduit 208 is filtered through filter 222 flowing to an injection pump 230 outlet conduit 228. Excess fuel is returned to the control device and is then directed either back to the tank 202 via conduit 234 or is mixed with incoming fuel via conduit 235 and a two-position temperature responsive diverter valve 290. The restriction and check valve provide the benefit of allowing a continuous air bleed to purge any incoming air or vapor from the fuel supply system back to the fuel tank 202, while preventing unfiltered fuel flow from the fuel return outlet port to the filtered fuel outlet port.
