Abstract (en)

[origin: DE10048695A1] The pump has a driven rotor (16) and a stator (14). A circumferential pump channel (22) formed in the rotor and defined by the stator contains the side channel and runs in a spiral coil round the rotor, i.e. more than one winding. A channel wall which defines the sides of the pump channel projects away from the rotor and runs in a coil whilst the stator has a smooth surface in the region of the pump channel.
