<p>An impeller for a pump, particularly for a cooling water pump of an internal combustion engine, includes a hub ( 11 ), a cover disc ( 14 ) which is disposed on the intake side and is provided with a central opening ( 15 ) for sucking in a conveyed medium, and at least one blade ( 13 ) that is connected to the cover disc ( 14 ) located on the intake side so as to form a single piece therewith and is provided with an inner section ( 13 a) located in the region of the central opening and an outer section ( 13 b) located in the region of the cover disc ( 14 ). The impeller achieves a high degree of efficiency yet is easily produced by embodying the impeller ( 5 ) in a completely open manner on the pressure side lying opposite the cover disc ( 14 ) and by configuring the inner section ( 13 a) of the blade ( 13 ) in a three-dimensionally bent manner while configuring the outer section ( 13 b) thereof in an essentially two-dimensionally bent manner.</p> |
