Abstract
Die Erfindung betrifft ein Kühlsystem (1) in einem Kraftfahrzeug mit einem Kühlkreislauf, in welchem zumindest ein Verbrennungsmotor (2), eine Pumpe (3) und eine Kühleinrichtung (4) angeordnet sind, wobei
- eine die Pumpe (3) umgehende Kurzschlussleitung (5) vorgesehen ist, die eine Druckseite mit einer Saugseite der Pumpe (3) verbindet,
- im Bereich der Kurzschlussleitung (5) eine Ventileinrichtung (6) vorgesehen ist, die zumindest zwischen zwei Stellungen verstellbar ist,
- in der ersten Stellung der gesamte Kühlmittelstrom durch die Kurzschlussleitung (5) und in der zweiten Stellung vorzugsweise der gesamte Kühlmittelstrom durch den Verbrennungsmotor (2) und nicht durch die Kurzschlussleitung (5) strömt.
The invention relates to a cooling system (1) in a motor vehicle with a cooling circuit, in which at least one internal combustion engine (2), a pump (3) and a cooling device (4) are arranged
a short circuit line (5) which bypasses the pump (3) and connects a pressure side to a suction side of the pump (3),
in the region of the short-circuit line (5) a valve device (6) is provided, which is adjustable at least between two positions,
- In the first position, the entire coolant flow through the short-circuit line (5) and in the second position, preferably the entire coolant flow through the internal combustion engine (2) and not through the short-circuit line (5) flows.
