Centrifugal pump i.e. cooling fluid pump, for internal combustion engine of automotive vehicle, has plate with aperture and/or gap between wheel and casing for connection of chambers, so that volumetric flows are conveyed to outlets

摘要

The pump has a running wheel (3) dividing a pump casing (1) into a pumping chamber (4) on a side of shovels (3b) and into another pumping chamber (5) on an opposite side of the shovels. A plate (3a) of the running wheel comprises an aperture (7) and/or a circulating gap (8) between the running wheel and the pump casing for a flow-technical connection of the pumping chambers, so that partial volumetric flows of intake volume current of pressure levels are conveyed to outlets (4a, 5a) with rotation of the running wheel. One of the outlets is connected with a heating circuit.
