摘要： A fuel supply apparatus for a diesel engine includes a fuel tank and a fuel injection pump. The fuel injection pump has an inlet and an overflow outlet. A fuel feed line connects the fuel tank to the inlet of the fuel injection pump. A fuel feed pump is disposed in the fuel feed line to supply fuel from the fuel tank to the fuel injection pump. A fuel filter is disposed along the fuel feed line. A main fuel return line connects the overflow outlet of the fuel injection pump to the fuel tank. An auxiliary fuel return line connects the overflow outlet of the fuel injection pump to the fuel feed line at a position upstream of the fuel filter. A control valve is disposed in the auxiliary fuel return line to selectively block the latter. A device drives the control valve in response to the temperature of fuel in the fuel filter so that the control valve will block the auxiliary fuel return line only when the temperature of fuel in the fuel filter is higher than a preset value.

摘要： A fuel filter is disposed in a fuel supply line connecting a fuel tank to a fuel injection pump of a diesel engine, and provided with a fuel passage through which a warmed overflown fuel from the fuel injection pump is supplied to the upstream side of a filter element of the fuel filter. A check valve is disposed in the fuel passage of the fuel filter and adapted to be openable to allow the warmed fuel to flow through the fuel passage. Additionally, a bimetal element is disposed to be operatively connectable with the check valve to cause the check valve to open in response to the temperature of the fuel within the fuel filter.
