Abstract

Ein Flüssigkeitskühlsystem (10) für eine Verbrennungs­ kraftmaschine umfaßt einen ersten Kühlmittelkreislauf (18-30) und einen zweiten Kühlmittelkreislauf (48-60). Der erste Kühlmittelkreislauf (18-30) umfaßt einen Radiator (18) sowie eine flüssigkeitsgekühlte Wärmequelle, während der zweite Kühlmittelkreislauf (48-60) einen Radiator (48) sowie einen Luft-Flüssigkeit-Wärmeaustauscher (52) umfaßt. Eine Flüssigkeitspumpe (22) ist zwischen die beiden Kühlmittel­ kreisläufe geschaltet und ermöglicht eine unabhängige Kühlmittelströmung durch die beiden getrennten Kühlmit­ telkreisläufe. Diese Pumpe (22) weist hierfür ein Flügelrad (64) mit einer scheibenförmigen Wandung (78) auf, auf de­ ren sich gegenüberliegenden Seiten eine Vielzahl von Schaufeln (76, 80) unterschiedlicher Konfiguration vorge­ sehen sind. Die scheibenförmige Wandung (78) bildet zu­ sammen mit dem Pumpengehäuse (62) zwei separate, von­ einander unabhängige Flüssigkeitskammern (70, 72). A liquid cooling system (10) for combustion Engine includes a first coolant circuit (18-30) and a second coolant circuit (48-60). The first coolant circuit (18-30) comprises a radiator (18) as well as a liquid-cooled heat source during which second coolant circuit (48-60) a radiator (48) and an air-liquid heat exchanger (52). A Liquid pump (22) is between the two coolants circuits switched and enables an independent Coolant flow through the two separate coolants tel circuits. For this purpose, this pump (22) has an impeller (64) with a disk-shaped wall (78) on which opposite sides a variety of Shovels (76, 80) of different configuration are pre are seen. The disk-shaped wall (78) forms together with the pump housing (62) two separate, from mutually independent liquid chambers (70, 72).
