Patentansprüche:Patent claims: 1. Kreiselpumpe für flüssigkeitsgekühlte Brennkraftmaschinen mit zwei getrennten Kühlmittelkreisläufen, die mittels fliegend gelagertem und zweiseitig beschaufeltem Radiallaufrad das Kühlmittel in zwei getrennte Druckringräume fördert, die über einen Dichtspalt zwischen Gehäuse und Laufradumfang verbunden sind, dadurch gekennzeichnet, daß zur Vergrößerung des umfangseitigen Dichtspalts der von der Beschaufelung mit der geringeren Förderhöhe geförderte Kühlmittelstrom axial abgelenkt ist und der Dichtspalt (12) sich durchgehend etwa über die halbe Laufradbreite erstreckt.1. Centrifugal pump for liquid-cooled internal combustion engines with two separate coolant circuits, the coolant by means of overhung and double-bladed radial impellers promotes in two separate pressure annulus spaces, which have a sealing gap between the housing and Impeller circumference are connected, characterized in that to enlarge the circumferential sealing gap conveyed by the blading with the lower delivery head The coolant flow is deflected axially and the sealing gap (12) extends continuously approximately over the half the impeller width extends. 2. Kreiselpumpe für flüssigkeitsgekühlte Brennkraftmaschinen nach Anspruch 1, dadurch gekennzeichnet, daß das Lager (2) auf der Laufradseite mit der geringeren Förderhöhe angeordnet ist.2. Centrifugal pump for liquid-cooled internal combustion engines according to claim 1, characterized in that that the bearing (2) is arranged on the impeller side with the lower delivery head. 3. Kreiselpumpe für flüssigkeitsgekühlte Brennkraftmaschinen nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß ein Mengenausgleich zur Rückführung der Dichtspaltverluste an druckloser Stelle erfolgt.3. centrifugal pump for liquid-cooled internal combustion engines according to claim 1 or 2, characterized characterized in that a quantity compensation to return the sealing gap losses to unpressurized Place takes place.
