Abstract
A device for heating and cooling fuel to maintain the temperature of fuel delivered to an engine within a desired temperature range includes a body (10) having a fuel inlet (12) and a fuel outlet (14). The body includes a middle portion (16) and a first heat exchanger portion (18) in connection with a heat source. The body also includes a second heat exchanger portion (20) in connection with a heat sink. A thermostatic actuator (86) positioned adjacent the outlet of the device, includes a plunger rod (88) that extends responsive to increased temperature of the fuel passing the actuator. A movable member (74) is positioned by the plunger rod to direct fuel to either a first opening (28) from which the fuel passes through the first heat exchanger portion and is heated, or to a second opening (30) from which the fuel passes through the second heat exchanger portion and is cooled. Fuel passing through the device is divided between the first and second heat exchanger portions to maintain the fuel delivered from the device within the desired temperature range.
