Jet pump i.e. oil pump, for conveying operating medium and/or cooling medium in internal combustion engine i.e. diesel engine, of vehicle, has spin generator provided in flow of direction before or within region of mixing chamber

摘要

The pump has an inlet (1) i.e. nozzle (6), delivering a drive flow under a pressure, and an intake connection (2) intaking an intake flow. A mixing chamber (3) produces a mixture of both drive and intake flows, and an outlet (4) is downstream to the mixing chamber. A spin generator (5) is provided in a flow of direction before or within a region of the mixing chamber. A cylindrical-shaped section (7) is provided at an end of the nozzle, and the spin generator is attached at region of the cylindrical-shaped section of the nozzle.
