Abstract

An ejector pump is adapted to pump liquid out of an enclosed space and simultaneously to maintain a vacuum within this enclosed space. A suction connection 2 for removal of gaseous media is disposed adjacent to a propellant nozzle 7 for entry of a propellant jet of liquid so that the gaseous media is drawn into a premixing tube 8, the outlet of the premixing tube 8 communicates with a mixing chamber 4 also in communication with a suction connection 9 for the liquid, whereby the liquid is drawn off at a location well down stream of the suction connection for the gaseous media. The controlling factor becomes the partial pressure created by the liquid employed for the propellant jet and this may be chosen accordingly.
