ABSTRACT:
A jet pump has an inlet, an outlet, a flow path communicating the inlet with the outlet, and a high pressure motive fluid inlet. The motive fluid inlet communicates with the flow path via a motive fluid control valve disposed within a nozzle assembly. A jet of motive fluid is directed toward the outlet by the nozzle assembly in order to pump fluid from the inlet to the outlet via the flow path. The nozzle assembly includes an actuator operatively connected with the control valve to selectively control flow of motive fluid in accord with a pressure difference between the motive fluid and a selected and possibly variable reference pressure.
