Abstract
A thermal recirculation valve (TRV) is described that provides for effective fuel module heating during cold operation to mitigate fuel waxing or gelling issues. The TRV allows for the control of heated return fuel flow into the module dependent upon the module's outlet fuel temperature without the return fuel directly contacting the wax element. The wax element is isolated from direct contact with the higher temperature return fuel through use of an elastomeric seal which prevents return fuel from directly contacting the wax element. In addition, the wax element is positioned in the fuel outlet of the module.
