ADDITIONAL FUEL SUPPLY DEVICE FOR A FUEL TANK, CAPABLE OF PREVENTING THE EFFICIENCY DECREASE OF ENGINE SINCE BACK PRESSURE OCCURS ON A FUEL LINE

摘要

PURPOSE: An additional fuel supply device for a fuel tank is provided to prevent the performance decrease of engine without the change of the inner structure of a fuel pump module and to enable the fuel of a sub tank to be easily supplied to a main tank since a fuel tank is divided to the main tank and the sub tank.;CONSTITUTION: An additional fuel supply device for a fuel tank comprises an inlet pipe(10), a branch unit(20), a connecting member(30), a nozzle unit(40), a filter unit(50), a jet pump, a mixing unit, and an injection line. The inlet pipe is installed in a sub tank and is connected to the return line of engine. The return line receives fuel through the fuel pump module of a main tank and returns some of the fuel. One side of the branch unit branches to form first and second fluid paths. The connecting member connects the branch unit to the inlet pipe. The nozzle unit forms first and second nozzles, which are connected to the first and second fluid paths. The filter unit is coupled to the second nozzle.;COPYRIGHT KIPO 2011
