This patent describes an apparatus for ejecting non-condensible gases from a closed Rankine cycle motion producing system including a boiler, an engine, a condenser and means for circulating a condensible working fluid in a closed path through the boiler, engine and condenser, the apparatus comprising: a valve having an inlet connected to the closed path, an outlet and a valve element controlling the flow of fluid between the inlet and the outlet; a fluid ejector including a power fluid inlet, an ejection fluid inlet and an outlet and being operative upon flowing a pressurized power fluid from the power fluid inlet to the outlet, to create a reduced pressure at the ejection fluid inlet, the ejection fluid inlet being connected to the valve outlet; a reaction chamber connected to the power fluid inlet and adapted to contain an exothermic chemical reaction which provides a pressured power fluid as a product; at least one reactant chamber for containing a reactant for the exothermic chemical reaction and connected to the reaction chamber; means for controlling the flow of the reactant from the reactant chamber to the reaction chamber.
