Jet pump for fuel supply in vehicles consists of primary and secondary convergent nozzles with a divergent nozzle connected directly to the secondary convergent nozzle requiring no intermediate mixer

摘要

The jet pump consists of a primary converging nozzle (10), which acts as the driving nozzle supplying fluid under pressure, a second converging nozzle (20), acting as the re-entry nozzle, surrounding the primary nozzle and connecting with the vacuum inlet (22) and the divergent outlet nozzle (40), forming the diffuser. The secondary nozzle, forming the re-entry nozzle, is connected directly to the divergent nozzle, without any intermediary mixing.
