Fuel feeder in diesel engine

Abstract

Abstract PURPOSE:To prevent clogging of the fuel due to deposition of wax included in the fuel in such a way that a return tube for return fuel to a fuel tank is branched to be two paths, and when it is cold, hot return fuel can be returned near to a fuel suction pipe. CONSTITUTION:A fuel return tube 20 in a fuel tank 11 is branched to be a fuel hot return path 21 and a fuel cold return path 22, and a temperature change-over valve 23 is provided on a diverging point. When the fuel in the fuel tank 11, is at a high temperature, return fuel flows from a fuel suction tube filter 16 through the temperature change-over valve 23 to a fuel hot return path 22 which has its opening at the position far distant, and when the fuel in the fuel tank 11, is at a low temperature, the return fuel flows through the temperature change- over valve 23 to a fuel cold return path 22 which has its opening near the fuel suction tube filter 16.
