Abstract (en)

[origin: WO2010003707A1] The water jet type pump (2) is part of a system (1) for generating an ultrahigh vacuum HV. The pump comprises at least one pump chamber (11) through which an ionic fluid (F) flows at high velocity. The chamber (11) comprises a first fluid feed (3) for the fluid F, said feed ending in a nozzle with a nozzle opening (3a), and a fluid discharge (5). A second feed (4) of the pump chamber (11) is connected to a high pressure chamber (10) to be evacuated. Gas is suctioned out of the high vacuum chamber (10) through the second feed (4) by way of the flowing fluid jet, which is used to discharge the gas out of the pump chamber (11).
