Controllable coolant pump for use in cooling circuit of combustion engine, has spring element generating radial bias force and binding torsional vibrations, and wings rigidly arranged on impeller that is arranged at pump shaft

摘要

The pump has a propelled pump shaft (1) arranged in a coolant pump housing (23), and an impeller (2) rotational-fixedly arranged at the pump shaft. Multiple wings (3) are rigidly arranged on the impeller. A slider pot (5) is provided with a cover surface (7) and wing guide slots (8) that are arranged on the cover surface. A spring element (19) generates a radial bias force, and binds torsional vibrations. The impeller and the slider pot are formed as sliding partners that are made from different materials such as metal and plastic.
