摘要： An ejector 110 having an additional nozzle 173 for issuing a fluid at a relatively high pressure through a throat 113 of the ejector 110 into an outlet 114 from the throat 113, so as to clear any material lodging in the outlet 114 and/or the throat 113. The additional nozzle 113 may be co-axial with the main nozzle 140 of the ejector 110, or angularly disposed from it.

摘要： An improved arrangement for feeding a cool liquid into a pressure vessel and mixing the fed liquid with hot vessel-contained liquid includes an ejector thermal sleeve within an inlet nozzle. An upstream portion of the sleeve sealed to the nozzle surrounds a supply line through which a main feed flow is conducted to a sparger outlet port in the vessel. Cool leakage liquid flow is confined within the sleeve and ejected from an ejector chamber formed around the port by a downstream portion of the sleeve. The leakage liquid is ejected by and with the main feed flow away from the nozzle whereby thermal cycling and cracking thereof are substantially reduced.

摘要： an oil well completion comprising a well bore drilled from the surface through and below an oil producing formation to provide an extension below the producing formation, a jet pump in the extension below and in communication with the producing formation, means for conducting power fluid under pressure downwardly in the well bore from the surface to the jet pump, and means for conducting spent power fluid, and fluid from said producing formation discharged by said jet pump, upwardly in the well bore from the jet pump to the surface. The purpose of locating the jet pump in a downward extension of the well bore below the producing formation is to provide sufficient submergence of the jet pump to avoid cavitation, without curtailing the flow of fluid from the producing formation into the well bore.

摘要： A short, wide angle diffuser having means for preventing boundary layer separation is disclosed. The means includes means for injecting a fluid stream into the diffuser at preselected locations for mixing with the boundary layer fluid. The injected fluid may be derived from the fluid exiting from the diffuser and fed back into the diffuser.

摘要： An eductor jet pump including a venturi throat mounted at the input end of a discharge line into which a high velocity fluid jet nozzle is directed. Hydraulic cylinders and a hydraulic control circuit provide for relative movement of the jet nozzle toward or away from the venturi throat for either pulsating operation by regular cycling of the nozzle portion, for specific control of efficiency by nozzle position, or for closing the venturi throat to prevent backflow.
