Abstract
Apparatus, systems and methods for pumping fluids, including for the purpose of controlling temperature and pressure in a propellant tank include a type of novel ejector, consisting of a typical ejector and an isolation valve integrated on the inlet of secondary fluid to an ejector, or suction chamber. The inlet valve is actuated by the application of the primary motive fluid pressure to a motive nozzle. The ejector is configured to operate when submerged in the secondary fluid.
