Abstract

A Rankine cycle device includes a heat exchanger for supplying heat to a working fluid and an expansion device for expanding the working fluid. A valve is disposed between the heat exchanger and the expansion device and a cooling device is reduces a temperature of the working fluid. A pump moves the working fluid through the Rankine cycle device and a sensor is used to sense a pressure of the working fluid. A controller is operable to open the valve based upon the sensed pressure of the working fluid.
