Abstract: A Venturi type ejector having a feed duct for feeding fluid under pressure with the duct extending along a central axis. A first expansion chamber is connected to the feed duct; a first mixing chamber is connected to the expansion chamber; a first suction chamber is connected to the mixing chamber; and an exhaust chamber is connected to the first mixing chamber. The ejector where the fluid under pressure penetrates into the first expansion chamber along a plurality of directions extends in a plane that is substantially orthogonal to the central axis. A vacuum generator includes such an ejector.
