    Definition Treibmittelvakuumpumpe, bei der die Teilchenanzahldichte des zu fördernden Gases im Treibmittelstrahl so niedrig ist, dass die Gasteilchen in den zum Vorvakuum freiexpandierenden Strahl durch Diffusion eindringen und einen Impuls in Förderrichtung erhalten Reference DIN 28400-2:1980: Vakuumtechnik – Benennungen und Definitionen – Vakuumpumpen, S. 7

    Definition a vapour pump in which the pumped gas flows into a vapour stream under conditions in which molecular flow predominates. Momentum is transferred from the vapour to the gas carrying it along in the direction of the stream. Pump fluid is heated in vacuumto generate the vapour which is directed through a nozzle. It expands freely in the stream before it reaches a cool wall where it condenses and is returned to the boiler to begin a new cycle Reference "IUPAC. Compendium of Analytical Nomenclature. Definitive Rules 1997 12.4.4 Vacuum technology http://www.iupac.org/publications/analytical_compendium/Cha12sec44.pdf [2.12.2009]"
