Abstract (en)
[origin: WO2013068512A1] In a centrifugal pump (1) for delivering liquids in a motor vehicle, annular webs (22 - 24, 28, 29) project into a gap seal (17) between a housing part (16) and a cover disc (16) of a rotor (9). The webs (22 - 24, 28, 29) are arranged on both components of the housing part (16) and of the cover disc (15) and delimit chambers (25 - 27) which accelerate, decelerate and divert a flow. In this way, the gap seal (17) has a high throttling action.
