Abstract

Die Erfindung betrifft ein Kühlsystem mit regelbarer Kühlmittelpumpe für flüssigkeitsgekühlte Brennkraftmaschinen, insbesondere in Nutz- oder Kraftfahrzeugen, mit einem Pumpenlaufrad und mit einem die Durchflussmenge regelnden Regelelement. Erfindungsgemäß ist die Kühlmittelpumpe (4) mehr-, insbesondere zweiflutig mit mehreren, insbesondere zwei, jeweils voneinander getrennten Kühlmittelkreisen zugeordneten Pumpenfluten (34, 35) ausgebildet ist, wobei wenigstens eine der Pumpenfluten (35) mittels des Regelelementes (21) hinsichtlich ihrer Förderleistung veränderlich ist.

The invention relates to a cooling system with controllable coolant pump for liquid-cooled internal combustion engines, in particular in commercial vehicles or motor vehicles, with a pump impeller and with a flow rate regulating control element. According to the invention, the coolant pump (4) is designed to have a plurality of pumping passages (34, 35), in particular two, in each case separate coolant circuits, wherein at least one of the pumping passages (35) is variable in terms of its delivery rate by means of the regulating element (21) is.
