Abstract (en)
[origin: US2001043871A1] A pump has a housing plate, a housing can fixed to the plate and defining a chamber on a back face thereof, a bearing sleeve in the can fixed to the plate and extending rearward from the back face along an axis, and a rotor shaft extending axially through the sleeve. Bearings support the rotor shaft in the sleeve and an impeller is carried on the rotor-shaft front end. A rotor body fixed to the shaft rear end extends axially forward in the can around the bearing sleeve. The rotor body defines an annular space around the bearing sleeve and is formed with at least one axially throughgoing passage open axially forward into the space and axially rearward into the can. A vane in the passage is angled for pumping liquid from inside the can axially forward into the space on rotation of the rotor about the axis.
