Abstract (en)
[origin: EP0841486A2] Fluid medium (f) is conveyed by contact with a rotating pump fluid (v), which can provide a rotating flow of the pumping medium for providing a centrifugal pumping force. The pumping fluid may be fed, tangentially, into a rounded chamber (14), with the rotation velocity being increased by the reduction of chamber's cross-section, and the chamber having at least, one outlet (24) for fluid in the vicinity of its mantle (141).
