摘要

Impeller (1) of a freely surfaces sucker,with a rotor disk (2), and with the rotor vanes (3), which essentially run radially and on the rotor disk (2) are arranged upright,characterized by the,that a rotor vanes (3) on its of the rotor disk (2) opposite edge of a wind deflector web (7) which, in comparison to the other, of the rotor disk (2) upwardly extending, standing surface of the rotor vane (3) in a lying orientation, to the rest of the surface of the rotor vane (3), runs.
