Abstract (en)

[origin: EP0990799A1] The engine has a housing with rotor (6) having pump rotors (10a,b,c), an inflow housing (2) and an outflow housing (1). The rotor is born in a bearing part, which also serves as fastening for the pump. A flow guide housing is integrated with the bearing part. Stationary guide blades (11a,b) are positioned between neighboring pump rotors. The three-stage pump has two intermediate housings (3,4) between inflow and outflow housings.
