Abstract
Inefficiencies in charging a closed cycle Rankine apparatus with working fluid and removing non-condensibles from the system are avoided in a Rankine cycle system which includes a source of pressurized fluid 60 and an ejector 64 having a pressure fluid inlet 66, an ejection fluid inlet 68 and an outlet 70, the latter being connected to a reservoir 46 for working fluid. A selectively operable valve 62 interconnects the source 60 and the pressure fluid inlet 66 while the ejection fluid inlet 68 is connected to the remainder of the system. When the valve 62 is operated, the reservoir 46 is pressurized by the pressure fluid as well as non-condensibles in the system entrained therewith withdrawn via the ejection system inlet 68 to charge the system with working fluid.
