摘要： A thermostatic valve for a diesel fuel system includes a valve housing and a valve element movable within the housing between a position directing heated diesel fuel returning from an engine to the inlet of a fuel pump and a position dumping the fuel into a reservoir where the fuel mixes with lower temperature fuel. A temperature responsive thermostatic element moves the valve element in response to the temperature of the diesel fuel. A temperature relief valve is provided in the housing to dump the returning fuel into the reservoir if the temperature reaches a temperature indicating overheating of the fuel. The temperature relief valve is a bi-metal valve mounted in an end wall of the valve housing.
