Method for adjusting flow rate exhausted into a vacuum generator and vacuum generator with adjustable flow rate

摘要

The invention relates to a vacuum generator (1) of the type comprising at least one nozzle (2) and a compressed air mixer (3) communicating with a vacuum chamber (4). This vacuum generator (1) is characterized in that the nozzle (2) and/or the mixer (3) are formed of at least two elements (7A, 7B) assemblable along a joint plain (9) to permit the possible insertion in said joint plain (9) of at least one spacer (8), the spacer (8) permitting a modification of the passage cross section of the nozzle (2) and/or of the mixer (3) as a function of the choice of the flow rate to be drawn into the vacuum chamber.
