    摘要: 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.

    摘要: A pneumatic flow-control system and method for an aircraft provide efficient mixing of high-pressure engine bleed air with one or both of low-pressure engine bleed air and ambient air. A controller determines an amount of high- and low-pressure air and ambient air to provide based on ambient air temperature and pressure and a flow rate and temperature of the mixed air for improving engine performance during different phases of flight and for reducing a burden on an environmental control subsystem of the aircraft.

    摘要: An ejector includes a body including an inflow space into which a refrigerant flows, a passage formation member disposed inside the body and having a conical shape, and a nozzle passage having an annular cross section functioning as a nozzle and a diffuser passage having an annular cross section functioning as a pressurizing portion between an inner wall surface of the body and a conical lateral surface of the passage formation member. A drive mechanism that displaces the passage formation member along a center axis is coupled to an upstream actuating bar which extends from the passage formation member toward the inflow space and is slidably supported by the body. A largest outer diameter portion of an annular member forming a wall surface of the nozzle passage provides a throat portion functioning as an edge for enlarging a passage cross-sectional area to cause a separation vortex in the refrigerant.

    摘要: A vehicle fuel pump module includes a jet pump assembly and feed tube that delivers fuel to the assembly. The module includes a jet pump choke that is disposed in the jet pump assembly and provides a reduction of pressure of fluid within the jet pump assembly. The jet pump choke includes include a choke housing that defines a passageway that extends between a fluid inlet and outlet, and a slot that is formed in a surface of the passageway. A ball is fixed within and obstructs the passageway, and abuts the slot. A fluid path defined between the ball and surfaces of the slot provides fluid communication between the fluid inlet and outlet of the choke housing.
