Abstract
A heater valve for a diesel fuel system for a vehicle having a main body portion with a fuel inlet and a fuel outlet adapted to be coupled to the vehicle fuel system. A fuel inlet line and a fuel outlet line from the valve are adapted to be coupled to a heat exchanger. A fuel distribution chamber in the valve is in fluid communication with the fuel inlet and the fuel outlet line and a fuel mixing chamber in the valve is in fluid communication with the fuel inlet line and the fuel outlet. A port opens into the mixing chamber and a spring biased valve in the mixing chamber has a restrictor normally restricting the size of the port opening with a valve shaft extending through an opening in a partition wall into the distribution chamber into engagement with a calibrator. A temperature sensor is associated with the valve for sensing the temperature of fuel in the mixing chamber and moving the valve to open both the port and the opening in the partition wall to allow fuel to flow into the mixing chamber from the distribution chamber.
