Another check valve allows the pumped liquid to return in a suction stage to the chamber. An injector valve between the liquid-piston chamber and the evaporator returns jets of condensed working fluid to the evaporator in successive brief spurts responsive to periodic pressure pulses in the liquid-piston chamber.
