    Abstract: Additively-manufactured flow restrictors are provided, as are methods for producing additively-manufactured flow restrictors. In various embodiments, the additively-manufactured flow restrictor includes a flowbody through which a flow path extends, a restricted orifice located in the flowbody and providing a predetermined resistance to fluid flowing along the flow path in a first flow direction, and a first internal perforated screen positioned in the flow path upstream of the restricted orifice taken in the first flow direction. The flowbody and the first internal perforated screen integrally formed as a single additively-manufactured piece utilizing, for example, Direct Metal Laser Sintering (DMLS) or another additive manufacturing process. In certain embodiments, the first internal perforated screen may include an endwall and a peripheral sidewall, which is integrally formed with the endwall and spaced from an inner circumferential surface of the flowbody by an annular clearance.

    Abstract: An in-line continuous flow liquid-gas separator-pump includes a housing, a rotor, a plurality of tubular flow passages, and a plurality of gas flow passages. The rotor includes a rotor first end, a rotor second end, an outer surface, and an inner surface that defines an inner chamber in fluid communication with the purge gas outlet. The tubular flow passages are formed in the rotor and extend between the rotor first end and the rotor second end. Each tubular flow passage includes a fluid inlet that is disposed adjacent the rotor first end and in fluid communication with the liquid/gas inlet, and a fluid outlet that is disposed adjacent the rotor second end and is in fluid communication with the liquid outlet. The gas flow passages are formed in the rotor, and each provides fluid communication between one of the tubular flow passages and the inner chamber.

    Abstract: Flow restrictor assemblies including a monolithic flow restrictor and methods for manufacturing the same are provided. The monolithic flow restrictor is configured for disposing in a fluid passage of a housing body. The monolithic flow restrictor comprises a first end and a second end, a first screen at the first end and a second screen at the second end, and a series of cross-sectional portions between the first screen and the second screen. Each cross-sectional portion has a plurality of slots formed in a radially outer surface thereof for connecting a series of restricting orifices formed in the monolithic flow restrictor for tortuously conducting a fluid through the series of cross-sectional portions.
