Title: Pumping-ejector unit and process therefor

Abstract: The invention pertains to the field of jet technology and relates to an operating process which essentially includes feeding of a gas-liquid flow from an ejector into a chamber for supersonic flow conversion, where the gas-liquid flow is exposed to an abrupt expansion and, because of a reduction to the gas-liquid flow's density, a sonic or supersonic flow regime is provided. Further, the gas-liquid flow is slowed down by a pressure jump. The invention also relates to a device for realizing this process which essentially includes a pumping-ejector unit furnished with a chamber for supersonic flow conversion. The inlet of the chamber is connected to the ejector's outlet, the chamber's outlet is connected to a separator. The chamber for supersonic flow conversion defines a shaped cavity, diverging stepwise in the flow direction. The described operating process and related pumping-ejector unit ensures more reliable operation.
